Regarding deletions, someone wrote this while back, hope it helps:
________________________
this is a lightly moderated website with tons of different forums, one for every major company, and the posts violating ToS listed in the footer get nuked.
Site mods usually nix posts containing one of these things:
-
foul language and insults
-
names, personal info (PII) of employees or mgrs (c-level's ok as they are public figures)
-
threats
-
trolling
-
spamming (or tons of posts with the similar text)
-
impersonating someone in a misleading or deceptive manner
-
off-topic posts about politics, religion or race/nationality/ethnicity
-
direct advertising
-
illegal and proprietary content
that bullet number two is what gets most people in trouble, you start talking names here and they will nuke that post in no time.
(I've found this list on another forum's page, but I think it applies here as well).
