Both players got banned for talking about Casper in a different language. Casper asked them briefly to speak english and they refused. Speaking another language in my channel is permitted, but if any high staff tell you to stop it, then you've to follow it! The ban was after all een correct ban. Casper agreed that permban was to harsh, so both players are unbanned and lets hope both players wont make the same mistake again.
It should rather be an unban request than an admin abuse report, as the ban was correct.
Both players are unbanned, problem solved.
