Every post deletion has a box to check to notify the owner.. If there's a multi-post clean-up, sometimes the mods wont' check it because you can't give a description of why each of those posts individually were taken down because there might be different reasons.. It's real simple. Post are deleted for: 1) no specific topical content.. Likely all personal flame or whining.. 2) seriously off topic.. Leads to thread derailments when folks respond to an off topic post. 3) other rule violations.. Such as threats to members, family, pedo, beasty, etc... There are NOT many rules here.. The main tool USMB moderation uses to keep topics unique and readable is requiring "specific topical content" in every post in Zones 1 & 2..
