"Rlarps" want these threads removed because they are a brilliant case study in how to run a online clown op.
They are chockful of all sorts of neat tips & tricks that anyone who's interested in preventing these types of attacks in the future can study & spot before it spirals out of control.
Suspect that some emotional language algorithms were used to find the particular weak spots to exploit. These also may have been used before in the generals, but it's much harder to detect due to mass volume of posts.
In the Rlarp threads, the precise methods are in full view since they were isolated discussions.
So no surprise those who were responsible want to see them disappear asap.
