It's not that they shouldn't.
It's that they don't have to be.
An internet bulletin board is a private endeavor that is not subject to first amendment rights (that is strictly between a citizen and the government).
The moderators make the rules, can break the rules, can change the rules, and don't need to be fair.
This is their house, not ours.
If you don't like it, go start your own motor oil themed bulletin board....
