Right, I did notice as well that autovting has not been working since yesterday.
I remember the bid-bots days. Those bots would upvote your post less than the HIVE/HBD (STEEM/SBD then) you sent them to get upvote. Morever, some wouldn't upvote your post, and sometimes it was not possible to find a respondent to get your fund back.
I think bid-bots still continue on Steemit.
Steemit is a shithole - you should consider not being there.
