yeah, right...

Just look at the screenshot I posted below.

even tough abuse was presented you were dismising them all the time.

What should have I done in your opinion? You can ask your friend CurtainTwitcher I always forwarded all abusers reported to me to zombee. I forward all messages to him.
I have never seen the blacklist so why do you even think I was ignoring these messages? Zombee was the only one that could edit the blacklist so we (Aranda and me) told him all abusers we could find via the Sensei-Lounge-channel, because writing their names in public channels wouldn't be very smart since they could just create new accounts.

So why didn't you guys banned circlejerkers

As said above I didn't have any acces to the blacklist. I believed zombee was blacklisting these abusers and most of the time he did it pretty fast.
