Can’t follow more than 30 people at a time

Hey, long time no see. That's the case with my personal IG account, I've gathered over 22k followers in 3 months and after that I switched to another projects. Now I can't follow more than 30 people, for example before I was following 100 people every hour (yeah, was doing it manually). Is it 'cause I haven't been active with my acc and now it is treated like any other spam acc?
Would be happy to read some problem solving suggestions or at least some alternatives. Thanks in advance to…
