Their intent is all well and good but, from your description, it seems they are not capable of preventing this tool they've built for their own "fun" from being used from causing harassment and real life consequences for real people.

It sucks for the people using it in the way it was intended but I would hope that they would agree their "fun" stops being fun when it's actively harming people.

Legally, there's no requirement that you moderate a forum so that its contents can't facilitate the commission of a crime (outside of a few things like DMCA anti-circumvention). If this were the case, everyone would have to be extremely careful when discussing anything dangerous, and most people would be hesitant to participate in the discussion at all for fear of being exposed to liability.

In fact, even the person posting something like medical misinformation can't normally be sued.
