Well there you have it, doesn't get a whole lot OG-er than that.
The truth is that some people-- particular some developers-- were uncomfortable with Theymos' almost-anything-goes moderation resulting in a lot of discussion of illegal-sounding activities on Bitcoin.org that they didn't want to be associated with, so the domain name of the forum was changed. It was the same forum all the way through, and you can see that the content was all the same through the name change by looking at the wayback machine. A few moments googling will turn up this post I made back in 2019 about the history of the move:
https://bitcointalk.org/index.php?topic=5203621.0Interesting, I hadn't seen that thread before.
Whatever peoples' opinions were at the time (2011), the way the shepherding (moderation policy) panned out seemed to be beneficial for the forum as its still here after all these years.
Arguably 1-2 of the top 10 posters of all time are trolls, another is a bot -- they probably wouldn't have made it this long under more stern moderating conditions. But its a small price to pay for the wealth of ideas that transpired here during the last 12 years.
In more recent years, the well known fraudster Craig Wright ran into problems with the fact that Satoshi's writing contradicts his claims so he started paying people to say that Satoshi never posted here, implying that anything inconvenient said by Satoshi was fake.
Its possible to use the Wayback Machine to verify that the satoshi posts count has been the same since he left in 2010.
You can also see a lot of his posts via the web archive as well -- none of them have been altered:
https://web.archive.org/web/20110528035755/http://forum.bitcoin.org/index.php?action=profile;u=3;sa=showPostsI wouldn't be surprised if there was an archive of his every post on forum.bitcoin.org somewhere (other than here).
