would you mind explaining what mistakes were made? I am not on1xbit's side here but if the issue is on your post count it is possible that the manager deemed some of your post low quality or off-topic, that is why the manager didn't include some of your posts on the overall post count on the spreadsheet. anyway, I am just assuming here, it would be best to explain what mistakes were made, so people have an Idea of what actually happened.
Checked his post history thoroughly and observed that he was actually overpaid for a week(2 weeks payment at once) which is most probably why he didn't receive the payment for the next week.
I guess he didn't send them back the extra funds which were sent to him by mistake and that ended up getting him blacklisted from their campaigns. Seems like he deserved it even though I don't like 1xbit.
I don't think they will reverse their decision in this case unless he sends them back the extra funds and keeps trying to convince them.
This is obviously understandable and think this should be resolved if possible. Although I've not checked the spreadsheet If his name is still there but he shouldn't complain to the public when he knows that he should have politely refund the extra pay if necessary. Things like this happens almost everytime in different signatures, so I think he should just try to have a dialogue with the campaign manager, very simple!
