Suggestion: I recommend sending people their deleted posts.
I find it annoying to spend the effort to type a post, only to have it disappear into a bit bucket. If you want it gone, that's your prerogative, but I think it is a breach of etiquette for a forum to destroy information created by a forum user.
Now I assume you found the original post a breach of etiquette, so may feel that tit for tat is the right policy here. I'd consider an intentional breach of etiquette as an unnecessary escalation.
You can still see your own banned comments on your user page. This might be false for posts, I'm not sure.

This is my attempt to codify the informal rules I've been working by.
I'll leave this post up for a bit, but strongly suspect that it will have to be deleted not too long thereafter. I haven't been particularly encouraged to try responding to comments, either. Nonetheless, if there's something I missed, let me know.
