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.)
