Just like the title says.
Go on steemit , click on what's hot and you will see new posts 2-3 minutes old getting 40 + upvotes.
There is some1 with a ridiculous amount of accounts cheating the system, I dont know for what purpose exactly since he upvotes about anyone but this is just bad for the system I believe!
You can make the test yourself!
Update at 22:00 east time
The auto upvote bot seems to have stoped , they are probably set to upvote posts of certain categories between certain times.
