“Anonymous “ posting query? Forum History

[Mbitr]

As a person with a keen interest in history and bitcoin, I like to combine the 2. So, while I was looking through some of the first forum topics, threads and posts, I came across some interesting and slightly mystifying( to me anyway) posts.
Hopefully someone can help me clarify a few things.

1.There have been several posts by “Anonymous”, so I presume at the beginning of this forum you could register as a guest ? Is this true and then subsequently changed ?
Examples

https://bitcointalk.org/index.php?topic=127.0
https://bitcointalk.org/index.php?topic=184.0
https://bitcointalk.org/index.php?topic=441.0

2. Also, in the above topics, the “Anonymous “ posts have been edited at a later date - September 11th 2011. This editing was all done by a member - davidonpa . I can’t find any information for this member. Can anyone enlighten me.

Many thanks

All of these posts have likely been made by some users that have been removed.
Here are some examples of deleted accounts. (I don't know why they have been deleted.)

Here’s your answer:

Deleting accounts doesn't mess up any threads, like this thread. It just changes to anonymous, with no profile information. Post stays intact.

As you can see here, I only change the username to "Anonymous" on request.

Some people that asked for their account to be deleted managed to get it anonymized, although it is pretty rare to see, and I haven’t seen any anonymized accounts that did not take place quite a few years ago.

And if you want to see another strage combination, take a look at SyphirX's case (conserves the name, tagged as guest, and profile not accesible):

<...>
There is barely anything archieved from the early profile ID numbers that lead to one of those "The user whose profile you are trying to view does not exist." Type messages. I did find one though: https://web.archive.org/web/20120326034624/https://bitcointalk.org/index.php?action=profile;u=407 (https://bitcointalk.org/index.php?action=profile;u=407).

It turns out to be @SyphirX’s account. That account is not accesible, but does preserve the username tied to his posts (for example here: https://bitcointalk.org/index.php?topic=407.0). On this same thread there is a post by "Anonymous", which I figure relates to a requested to delete account as per the quote at the top of this post.

You can find some answers in these threads, better if you read the replies. These threads are available in Meta only, I don't know if there are other boards that explain it in detail but just reading the replies below I guess that will give you the knowledge to your question. And one more input, if there are things that you don't understand you better search for it on the search feature of forum first rather than creating a thread, just my piece of advice.

Many thanks DdmrDdmr and rhomelmabini. Definitely found out the information I required and more . I find some of these old threads very interesting.
rhomelmabini - I will certainly try to improve my searching skills, as searching for Anonymous brings up quite a bit !!
