While I haven't been aware of this issue and so far I don't think I've encountered any deletions of my posts/comments, I've got to give credit to UhtredRagnarok for wanting to bring this to the forefront and hopefully make things better knowing that he/she might be getting a lot of complaints, maybe rightly so (I really don't know).

In terms of temporary bans, seems like a reasonable penalty if applied correctly and consistently as there has to be some deterrent for inappropriate behavior.
