One of the reasons I was so angst-y at the time was because of moderator behavior. They had a whole system fleshed out with warnings that would be given and specific ban periods. The perm-banned status was rare, but existed with Chester and Solid Snake.
The mods of the time we an insular community of friends: there once existed a semi-private mod discussion forum, inaccessible to view for most, but you could see had more posts and was more popular than most of the non-GD sub-forums at the time. The numbers were bolstered by the numerous "local mods" created for sub-forums without posts. It was excessive, to say the least, for the size of the community.
But, it was also normal. Forum owners have always chosen their own mods. That it be merit-based, is a generosity.
Apparently he was doing something, you would have to ask someone who was here what it was doing to the site. He wouldn't tell me so I am unfortunately unable to tell you what "mess with the forums", not the site itself.
One iteration of the forum had a security flaw that would allow you full control over everything, the ability to change the color scheme of the forum, etc. Possibly even see passwords, if I'm remembering right. It was something like, URL/forum/secretsecret, but it was changed a couple times before it was fixed.
Every mod knew about it, which was a ton of people already, and I know for a fact some of them shared it with their friends (which is how I know about it), which means probably half the board knew.
It was pretty obvious that it could be used maliciously since the tag line when it was shared was "Don't tell anyone, but we do have a slight problem:"
I just can't believe that the idea of two people sharing a computer (for example, a married couple?) was some kind of impossibility to us.
