Tribe was great. Everything was ironic and fun and weird. There was a tribe for enthusiasts of "brown foods", for "paranoia" (in which we would post the truly most paranoid thoughts we could muster), for "evil geniuses" (tips on lairs, knowlege sharing on death rays), a tribe called "silence" wherein people would just post "ssssh". Another where we planned a dadaist amusement park. Another called "things on top of things" which were entirely photos of things that were on top of other things. Another for enthusiasts of Abercrombie & Fitch. Another called Extreme Honesty for people who wanted honest advice. Another called Bad Advice where people would out-compete each other for giving the worst possible advice on any topic. On and on.
There were definitely tribes where people would try to out do each other with warped and disturbing posts. Digging through tribe.net archives will find posts bragging about murder, pedophilia, bestiality, necrophilia, what-have-you. In that context they were intended as entertainment, rather like horror fiction, but in today's social media climate such a free wheeling context is incomprehensible.
