Biased Bans?

[PhilJHerman]

I was recently banned on the player Gran_Canaria and the stated rules I broke was "Insulting, flaming ooc" and "ooc chat in system chat"

The ban was for 7 days for the sentence "get out of here you worthless piece of crap" which I said as a Zoner to a Phantom who retreated from me. This is perfectly in bounds of role playing I thought. I guess I was wrong because I was banned for 7 days.

When I looked at other player bans I cannot help but see that there is a character that had violated more rules (Insulting flaming out of character, Occ chat in system, and having a police tag with a pirate ID) which only received a warning and a fine of 15million

This players violation is far worse than mine, and the player has more sanctions on other characters yet his punishment is much less than mine. I cannot help but think something is wrong?
