BlueHell has many unique etiquette of its own, that can't be found on any other IRC network. For example, if someone says an emo story about their life, one would say #care, to advertise the #care channel. Expectedly, you would click on it and join, and see the topic like "Welcome to #care - people who care," and you would see you're the only person there, or just you and the person who advertised it to you. Correspondingly, the person who advertises to you #care also registers the channel right before. This fad has spread to other related networks such as SysHackers.
Another form of IRC etiquette found only on BlueHell is the word rifk, which is the same as rofl. I dunno who started it, maybe it was werx. ;/
