Speaking of, I remember getting a PM from a mod when I was moderated, telling me why/what happened. That's a PM generated automatically by the forum's warning manager and sent as if from the warning moderator's PM outbox. I think you actually have to follow the link to the post that drew the warning to see why you got it.
And a fat lot of good that is when you do that and repeatedly get an 'Error' message 'cos the link is off limits to you and when you query this you get the same 'off limits' link again.
Now I've simply lost interest and a lot of respect for the moderation process on OC.net, very sadly.
You have very high expectations of internet forum moderators apparently. If you don't know why you got warned, just PM a mod. It isn't hard and it is pretty much the rule on every web forum known to mankind.
As a side note, complaining about the moderation process is also a good way to end up getting other color dots next to your name. This is my friendly assistance to you so when you get a yellow dot, you will know in advance why you got it.
