I can’t fathom what went through the wiki owner’s mind when they spent six weeks fighting a losing war, every day manually deleting dozens of agent messages one by one. As opposed to, say, switching the (dead for years) wiki to read-only, taking it down entirely, and/or starting to wonder what exactly was going on and doing some detective work, which might have uncovered OpenAI’s massive fuckups earlier.
There is also the possibility they don't keep up with modern AI development at all and then this looks like any old spam that will stop in a few days (as it did).
Now whether it is wise to keep an old page which such outdated behavior online is another question.
