It is no longer an official bidbot, so guess why it is still delegated by blocktrades.
themarkymark pays for the delegation ...
But yes, most topwitnesses are very close to each other, delegate HP to anonymous accounts, lend each other their posting keys (for example to disguise who is behind a flag), are able to put accounts on blacklists instantly, even if their names aren't officially connected to these lists.
Concerning STEEM you either have to beg @steemcurator01 for an upvote (after participating in any of these many competitions) or be Korean. ;-) There aren't the original communities anymore where normal users supported each other.
Anyway, enough said, isn't it? I didn't like when HIVE witnesses were posting and farming on STEEM after they had left, and now I also don't intend to discuss about HIVE all the way after I left.
