I used to be an avid reader of alt.best-of-internet. When AOL put newsgroups online, alt.best-of-internet was at the top of the alphabetical list and suddenly got a deluge of nonsense. Please to AOL went unheard.

Someone got the brilliant idea to keep a thread bumped to the top whose title was:

OFFICIAL MESSAGE FROM AOL: WE WORSHIP SATAN

I don't know if this was cause/effect, but shortly afterwards alt.best-of-internet was hidden or moved to a less conspicuous location in the UI and the deluge stopped.
