Nooo, I'd never do something like suspend a user for 5minutes because they exclaimed on a thread they were feeling left out because they'd never been suspended :)
Would be nice ....sometimes when threads are escalating into something unpleasant I really wish I had the power to protect them from their own silliness.... sometimes I think just a 10 minute break with a message that comes up on the screen saying calm down go and have a cup of tea would be really useful
