Okay, columbus said that and look what he found
All listed above are violations, so I would have to check all of them for a warning, but the degree of the offense you can't relay there and I think come down to one of two actions.
Spamming - auto ban, its know all over the web as a no no
Intentional multiple posting- Is that really a problem? delete the post and warn
Failure to post FULL NAME - minor offense when a person is new major when they have been advise and ignore it or troll warn then ban
Inappropriate advertising - again a know no no, lock them out
Private messaging abuse-using it to spam? that should be banned, other than that, people can delete them themselves and it should be self policed by the user unless it goes to the point of harrassment, one warning then ban them
Excessive flames- your on site warnings gets the point across, if it continues I don't think any amount of points will change what you would do
Antagonism towards moderators-should be no difference than toward another user, same as Excessive flames
Racist/prejudicial remarks- same as antagonism
Profanity- not nice, but should exclude @!$%@* Warn and then ban
Shotgun advertising in classifieds - I have no clue what that is
Obvious troll-same as flames
Posting off-topic messages -it happens at times and is innocent at times too, if not, move it and warn them.
IMO opinion, like I said before, seems like a lot of work when in fact warnings works usually, yes you have to repeat them at times, but whatever the problem is, if they don't heed it, your going to remove them. Everyone here knows who they are and who does not care for who's post. Everyone knows basic internet protocal, people get passionate about something dear to them and do go overboard at times... a reminder usually works MORE than you intend it to.
Then you have the point of time to ban... temp or perm, how long if temp, only you or the moderators can decide that depending on the offense and degree of it.... it usually boils down to one warning and then removal or locking out
