Advice: Provide the service before a customer pays (only for the first few customers) but keep his/her account until he/she has paid the required price. You have the recovery information, so if he/she attempts to take back the account without paying, you can always recover it back from that person. This will get you a few vouches so that people will be more willing to trust you.
On Topic: I have a perm banned (for botting) account that I would like unbanned. It has no appeals left however, and I can't recover the account =/
Would you still be able to get it unbanned?
