Ah yes. Anonymous unsigned guests. Stevie's 'obby 'oss. From the rules of the now sadly-defunct Gaughan forum:

2. No anonymous members.
It is a requirement of forum membership that you let the other members know who you are. There is not a single good reason in a forum of this kind for anonymity. If you are normally known by a nickname, by all means use it here; my birth name was Richard but the only people who ever use that are my parents (both dead) and my two sisters and their children. The no-anonymity rule is not here to check people's birth certificates, it is simply so that we all know who we're talking to and the risk of anonymous trolling is reduced. As said, by all means use a nickname on posts but please put your real name in your member profile and you will be asked to give it when registering.

So if you troll or otherwise post inappropriate stuff, as above, the mods know who you are and you're toast. Good, eh? As ever, only in m'humble, and this is never my gig.
