Name is considered inappropriate, but instead of the mod doing their job, they let it go because its their friend. I get it mods are "volunteers," but they should do their job unbiasedly instead of picking and choosing who to silence because its their friend. Do what you signed up to do and not because you want a green name. That is all.
Ain't you allowed to curse now as long as it isn't directed at anyone? The ign is not directed at anyone.
It's still considered inappropriate - a sexual act. I've seen names with simple innuendos get silenced. doesn't matter if its directed at someone.
