How to detect plagiarism

[bittraffic]

Based from my experience of reporting fake ICOs and plagiarized WhitePapers, I mainly use google and copy-paste parts of their paragraphs. If I see that parts of the highlighted texts are similar to different links provided in the search, then I consider it as plagiarism. The problem arises when someone checks the post history of a user as it would be very time consuming.

I believe that there are bots created by some users specifically functions to check plagiarized texts. I doubt that this was achieved by a single individual who took the time, effort, and patience to check millions of accounts in a short amount of time.

There are some users that can get away with plagiarism, some of these people are getting smarter but not using their smartness the right way. You may have to be on the look out of those text that replaces the letter "o" to  zero (0) or simply another font and because google bots doesn't understand it, your searches won't provide results and so you will think the user wrote the original text.

I was considering posting the above text as my own, but I wanted to first make sure doing so would not constitute plagiarism, so I copied this text into:
https://www.seoreviewtools.com/duplicate-content-checker/?text-input
https://www.duplichecker.com/
https://www.grammarly.com/

All three told me there are no results. I did the same with the text of a post I found that is nearly 9 months old, and got the same result. I believe a very common problem with plagiarism on the forum involves others' posts being copied.

You are so careful but I don't think if one write their own words, they will never be judged as plagiarism. How do I plagiarise others if I brainstorm, type my  own words to express my own ideas. Only lazy guys who copy and paste words of others will do have to do this. Hilariously, if they copy and paste, they don't need to use those tools to check they plagiarise or not.  I don't think plagiarisers will check their posts with above tools, because as theymos said scammers are always dumb, so I want to make further interpretation as spammers are mostly dumb.

I don’t think you understood my point. If I wanted to check both of those posts for plagiarism via the text of the posts, any plagiarism detector should tell me the text was plagiarized, with the source being the page the post is posted on.

Actually, this already happened to me several times already. Impulsively copying and pasting the whole paragraph without even checking/reading the entirety could lead to poor and inaccurate results. That is why it is important that before you check the paragraphs for plagiarism, read them first and apply the necessary changes.
Usually, paragraphs that contain special characters or converted letters to numbers (i.e. like what you just mentioned) raises suspicion and doubt on the validity of the sentence. Those are one of the few signs that the paper MIGHT be plagiarized or at least edited.

Unfortunately, I do not know any such bot that can bypass or detect plagiarized work with edited sentences. Manual checking may yield positive results but it may be too time consuming.

I think the most common reason why many newbies plagiarise is because they are not good with the English language contrary to the belief that they are here to spam. So, whenever they find a post with good English that also says what they wanna say, they copy paste or modify it a bit.

It wouldn't be a problem if you find a post that you like or that completely agrees with what you wanted to say and you copy it fully or a part of it. The problem is not giving credit to the original author of the post by posting the link where you got it from and explaining that you feel the same way as the person who wrote the post.

Writing in perfect English is also not a requirement to participate in discussions here. You can see a clear difference between a genuine post of a user wanting to be a member of the forum and someone who just wrote a bunch of nonsense for whatever reason.

Users don't notice that forum has quote button, which has its very powerful meanings:
- Saving time because users don't have to do copying and pasting with Crl+C and Ctr+V (in case they want to mention about ideas of others that posted in the forum).
- Preventing risks of forgetting credits/ sources of original places from which helpful contents taken for their posts.

By the way, rephrasing other posts is risky, because if posters don't leave original sources, their posts will be considered as a well-known type of plagiarism ⁽¹⁾. There are bots to do this, and sometimes it is difficult and takes times to investigate rephrased posts are made by human or bot. In my opinion, I don't think posters have good reasons to rephrase posts of others. They mainly do it to get post count.

The main point is to make it public to anyone reading the post that you are not the original author in anyway you want. If someone doesn't know the proper way to use the quote button or quote the post it still isn't a big problem. You can make it known that the post isn't yours in other ways.
For example, begin your post by saying

Code:

tranthidung said: xxxxxxxx

Every reported plagiarism post is checked by the forum mods, humans. By checking the report they would realize that a user didn't copy/paste since he is mentioning the original author and isn't claiming it as his own. The user would than receive advice by the mods and other members how to quote posts properly but he wouldn't be banned.

The topic made for plagiarism detection technique, but I think it is worthy to remind all users on how to avoid plagiarism.
[TIPS] to avoid plagiarism
In my topic, I suggested some solutions to avoid plagiarsim (more details presented in my topic):

1. Copying and pasting contents from other sources (outside the forum, such as articles, websites, etc.) without source links
1.1. Leaving the source link behind the content (definition of plagiarism, in this example)
1.2. Using quote block without exactly original source
1.3. Using quote block with source (author names, website links, etc.)

2. Copying and pasting contents inside posts/ topics of other forum members without quotes or source links
2.1. Leaving the link of my topic below contents that you copied from my OP
2.2. Using quote block without author names, or links (because you forgot where they are).
2.3. Using quote block with full link

This method of @Pmalek is good, too.

I prefer to use link to avoid plagiarism for external source. For internal source such as from comment on this forum i will tag user profile link or post link to make hyperlink to profile name. As Pmalek and tbtc_mt2 says. For making new thread on my local board i will always ask to thread creator first to get permission.

How to know or detect plagiarism, all of suggestion on first pages is a good stuff. You can also trying few website to make sure that contents is from plagiarized.

Why would you care to find plagiarism so actively lol? I think the most common reason why many newbies plagiarise is because they are not good with the English language contrary to the belief that they are here to spam. So, whenever they find a post with good English that also says what they wanna say, they copy paste or modify it a bit. Then after years, they gain reputation and boom, a ban comes.

I'm not complaining, but just saying that although plagiarism is a ban-able offense here, it shouldn't be on the "top" of your priority to actively look for them just for the sake of it.

I think your reasons cannot be forced, why you forbid people to do what I think is good, to reduce plagiarism.
and how they can get a reputation for posting plagiarism.
Lastly you say it doesn't have to be her/his top priority, in my opinion it doesn't matter as long as she/he does it right,and make the forum better.
