I did some edits to remove noise (e.g. https://superuser.com/review/suggested-edits/541897) in the "spirit" of askubuntu.com (where such an edit would be approved with 95 % probability in my experience although I don't know if that's good or not), but most of them were rejected which caused a block for editing. There's no info how long it will last or what I could do other than wait.
I don't disagree with the rejections. I was just trying to get n*2 rep to be able to place a bounty without loosing reviewing privileges and it wasn't right. I learned my lesson. The ban isn't for eternity, right?
