I did use bidbots briefly, during the time when SBD skyrocketed as a result of being introduced to Korean crypto exchanges. I did profit a bit from using them, but I didn't gain any real audience as a result, so I quickly saw that they were not going to be a long-term solution. Best-case scenario, you're paying for the right to gain reputation faster than you might otherwise.

But these days, reputation is meaningless. Get the wrong whale "triggered" and your reputation level drops to negative numbers in a flash -- even if you had the support of 1000+ other minnows and redfish. There are quite a few folks out there with high reputation levels, who absolutely deserve to be in the negatives based on some of the scummy/scammy stuff they've done on Steemit.

I agree with @modernzorker about using @steembasicincome -- SBI is better than a bidbot any day of the week.
