I can handle being called a lot, joking and in other wise. But imo faggot and nig*** are two words I can't tolerate anyone being called. Such horrible words and never ok. TNT filters are ridiculous but in this case I think they got it spot on.
Whether you meant it bad or not, you're on a site with kids on it and they have done their job in this case.
I don't like the way some filters work, especially the "killing" part you mentioned. I normally write long nms to my nfs, and it is so troublesome to go back and edit the nm when the message doesn't pass the filter..... only to find I wrote "skills" in that nm. I seriously don't get it.
