While the bandwidth displayed is likely just a problem caused by steemd using the "old" calculation from 0.19.0 not 0.19.1 (see https://github.com/steemit/steem/releases), this account still raises a bunch of flags!
The spam-posting in itself is worrying, but the voting on it looks especially fishy.
I will look into this further!
I tried to contact you yesterday via steemit.chat. Are you there from time to time ?
yes, and I saw your message, haven't had time to respond yet.
