The Sig limits are something that we expect members to handle/take care of themselves. It does not take much effort to find the Sig Guidelines thread or to PM a staff member to ask what the rules about it are, nor does it take much effort for one to make sure that he/she adheres to those rules. If a Sig goes over what's allowed and one of the staff sees it, then it gets removed and replaced with a note stating what the problem was and a link to the Sig Guidelines thread. It's how it's always been here.
