Celever, I did get warned, in the past, but for other, more... rare stuff.
If I don't get warned by things that would cause a warning for other people you'd have to ask the mods to get a concrete response... but I imagine that it could be because:
A: I have talked with them (see: warnings above), and they know my position on using that kind of language, and the PG-13 rating (hint: it's bullshit).
B: to them, my posts are not empty of meaning, insight or humor, and I have never used that language to insult anyone and mean it (which is against the rules of the forum)
C: I have actually lowered my usage of that kind of language; if you were to look up my first posts here, you'd notice that they are very different from now.
So I can't give you a definitive answer... but if you need one, talk to drohn, or juliacoolo... and I think athena or chaos too.
