"no one here can tell me who i can help and who i cant whatever the reason. i felt within my own judgment that i should help the guy out whether it be educational or evasion."

There is a big difference between educating someone about how bans work and intentionally helping with and suggesting they ban evade. We dont dictate who to help/not help, we do however ask that everyone respect the very few policies we set. As Cobra, Collective and Mentality all pointed out, one of those policies is that we do not help or encourage ban evasion.

"it would be very easy to ban him again"
sure, but then he has gone from a situation that was possible to amicably resolve, to seriously annoying the channel ops beyond discussion as well as being subject to the possibility of a kline for ban evading. Whatever the reason for the ban, far better to suggest the user discuss it with the ops in that channel to work it out.
