Hello.
The account appears to be engaging in a vote-trading scheme organised by "thranax":

"thranax" is a long-blacklisted user that used to engage in mass plagiarism fraud using multiple accounts.
To be removed from the blacklist, you would need to stop engaging with this scheme, please.
Since you removed the delegation, I deactivated the blacklist.
Thanks for removing have a nice day
