I 1000% agree, and like I said earlier, since reading that post referenced by Shebeen, I've have made sure not to say Spez anymore. The guy who brought it up explained his situation, which I understood and respected, and immediately changed my words. I have no way of knowing if the other guys did the same as their words would just have been changed if they said the wrong thing. On the issue of "should you intentionally say things to offend people", I think it's clear the world is a better place if we don't do that. (Who gets to decide what's offensive is a whole other can of worms)
A completely separate issue is automatically changing someone's words without telling them. I think that's egregious. Warning points, requests to not say offensive or derogatory things, banning people, even deleting intentionally offensive posts, etc, that all makes some sense. Actually changing what is said is something completely different. This might not even by the only thing thats auto-changed, and we just haven't noticed yet.
