I think myself and most of the mods....use a step by step type of infraction....as in.
1. Warn
2. Warn again, and possibly a PM.
3. Maybe even warn again, I usually do.
4. Warning infraction...
5. Maybe even another warning infraction, depending on if "please" was used.....*smiles*
6. Infraction, and possibly a couple more before a probo is given.
The thing is, in this little scenario...it is very evident that the person is "not just having a bad day".....is "not just being sarcastic"......is "not just kidding". They are in fact being rude, crude, and socially unacceptable. We want people to feel free to give their opinions here without being degraded for doing it. THAT is my standard.....and apparently it has been ok'd by the boss, because none of my infractions have been overturned....."well, except when I hit the wrong button....*cough*"....
There is too far.....it may vary from person to person, but there is a line that can be crossed, and when you cross it, and I see it.....I'll infract it. *smiles*.....with a smile.
