Then what account did you get banned on for ban evading then? Because it certainly isn't your main.
I think what happened is the following:
His friend hacked on OPBlocks, but on his own account at Ziggys house, and got banned.
Ziggy didn't know this, so he got OPBlocks on his main, and since his friend had hacked at his house, when he joined he had the same IP as when his friend got banned, so
Zigy got banned for ban evasion.
That's what I understand.
