I can't remember if this is a consistent pattern with just you, or if I keep seeing a variety of people ending posts like this, but I'll address this trend here and now:
1. We don't really care how much you swear as long as it isn't excessive
2. If you're ending your post in "hey please don't ban me for this post" you should think harder about the actual content of your post -- we will absolutely issue warnings/bans where we see fit in spite of this
3. You can use Talk to the Staff to ask if something is appropriate to post before you post it
In summary, adding the "please don't ban me" paragraph is unnecessary; in fact, it doesn't accomplish much besides wasting space -- just talk to us first if you're not sure if you can post something.
