Blocked from Following?

Hey I noticed I had a lot of accounts get blocked from following people lately and when the date is up and I start back following I see I get blocked again...Anyone else going through this or have been through this? What's the problem and how can I fix it.

How many accounts are you managing ? with bot or no ? You've followed too many private profiles (pending follow requests) ? Reached the 7500 follow limit ? Following too fast ?

IG sometimes do that for 24 hours+ Happened to me before, wasn't permanent.
