Bought account, got suspended *CAUTION*

Hello, I bought a level 60 dwarf paladin from mmoprovider, everything went smooth but later down the line after alot of playing and progression of my character, the account got locked. Now you may ask yourself why that happened? I got an email from blizzard that states "A player on this account used a different game account to take part in exploitative play. This is a result for account sharing, this wasnt the issue though, the issue is that the provider of the characters for mmoprovider uses identical names for every character he levels on faerlina which raises huge suspicion of account sale, who levels 30+ characters to play for their own sake? yeah nobody. Be cautious when dealing with these people.
