My thoughts on this subject were more towards rewarding users for reaching a certain level vs being able to come right in and join the campaigns. First of all, users need to learn about bitcoin and the forum before they pop in to come earn. The biggest thing is they need to learn how to read and prove they can read.
https://bitcointalk.org/index.php?topic=4505246.msg40559490#msg40559490 For example. It's clearly stated in this bounty thread on the twitter and facebook sections, that users need to fill out the form to get credit for their stakes. I don't know if users are just too lazy to read, cannot read English, or do not care about rules posted in bounties, but obviously 76 pages later you can see that quite a few do not follow the rules.
Maybe I need to be more of an asshole?
I am just thinking that users need a period when joining to where they need to l earn how the forum works. Must read certain stickies. Learn about bitcoin. Maybe even take a test before they're allowed to post in certain areas or earn a penny. The test itsself would need to be alot of different random questions about the forum, it's rules, and anything else in general whomever creates the test would wanna throw in. I would not suggest just using the same test for every single user because some dude will make a youtube video about the test and the answers and render the test worthless. It would need to be constantly changed up.
The forum can't refuse Campaigns-it's business. It's no secret that most of the forum users are people who have to earn their miserable cents in the advertised here projects. Remove these components and the forum will turn into an elite club of crypto-currency lovers.
You can not impose any restrictions, people are enterprising, will find ways to circumvent the prohibitions.
Moreover, it is impossible to introduce a fee-this will cause a growth in negative feedback and negative attitudes towards the forum.
The most reasonable solution against spam is the organization of work following the example of Yahoo:
1.The publication of authentication in the teem and the publication of reports in the form.
2. Means from bots is adding to the own post of authentication the captcha-answer,
for example:
link to the topic of the forum: the 1st word in the 5th sentence.
Thus, each user will learn to read articles about the crypto-currency).
