As someone who openly has an edgier sense of humour I have to say, I don't think chat has been that bad lately...in fact for the last few months it's been rather quiet so I'm not sure specifically what you're referring too but as there seems to be a lot of topics which disturb you I would recommend placing people on 'block' on chat or making your own room with either a password or specific rules.

You have to bare in mind that for a lot of people sex doesn't automatically mean rape or abuse and whilst it might not be appropriate to that room I have to honestly say I've certainly not seen anything in recent recollection that was explicit or inappropriate.

Emotional support can also take many forms....in fact I've always found it rather odd that we have a whole room dedicated to it, when we all visit chat for one form of support or another.

Maybe chat just isn't for you - and there's nothing wrong with that. Did you know you can create your own group of like minded people where you can discuss whatever you want? Perhaps this might be better for you.
