Well the case here is, I banned him from posting translations and before I had time to answer to his pms he posted again.
I'm a bit in a bind here since he went behind my back because he wanted to get paid.
I´m my new (in the forum) view, you did something wrong since the translation was correct and he acted before your answer because he was convinced that you had no reason to delete the posts.
If you have to moderate a whole section you have the right to make mistakes from time to time, but now that is clear that the guy is not spamming it may be the time to let him post and forget about the whole thing.
