Yep, I tried this a year or so on Instagram also. Literally just mindlessly following random users, didn't even have any content up. After 4000 follows I got 2500 followers in 2 days.
This is the same except now they are trying to monetize it. I sometimes feel bad for even re-steeming the @ocd posts to my followers cause I know its random content and most probably get annoyed cause they followed me for something else, but at least I'm doing it for free and for the greater good of the platform in mind.
That is funny you got so many followers in 2 days on Instagram using that strategy.
I wouldn't be worried about resteeming the @ocd stuff but one user on here told me that they won't follow someone who resteems a lot of stuff. I was actually surprised to hear that but she was saying that she doesn't want her feed all clogged up. It is tough to manage for sure.
I don't follow re-steemers either. (One, two, or even three resteems okay, if among many good quality posts.)
I miss all your usual posts. Haven't been hardly any lately.
