:Yeah, this. While there are more guidelines on Wikipedia than any human being could reasonably be expected to remember, a lot of them boil down to: don't be a jerk. As long as you approach this business with a mindset of "what do the rules let me get away with?" then you're probably being a jerk and can expect to be banned for it. When somebody tells you that not-signing is causing inconvenience and annoyance to other editors, perhaps instead of asking "do I have to stop?" you should ask "would it really hurt me to change?" AFAICT you haven't even offered a reason for your refusal to sign; rightly or wrongly, that gives other editors the impression that you're being stubborn just for the sake of it.
