I'm starting to tire of this pattern of behavior.
This is not IRC or TMO, not that this level of immaturity is acceptable on those media either. But this forum, in particular, commands a bit more respect.
If you want to ignore someone, just do it. There's no need to announce it or to try to belittle others before doing so. Doing either of those reflects more on YOUR immaturity than it does on that of the person you're trying to insult.
Keep in mind every time you do something like this now, you're not just damaging your own reputation, but that of the entire council.
