No time flat actions from a non botted account 5-6 percent ER. Shadow bans not this bad and it does not use hashtags. 114k account .
Those blocks and errors from a few days ago i think is a breakage of Insta somewhere. Not all accounts crippled I think it was just a random thing
On Thursday Instagram did an API update which broke things for a lot of people. I’m not talking individuals like you or I but your average user as well. There are still reports from people on twitter and down detector suggesting there are still issues for a number of people.
One of the biggest issues Thursday and reports since then are people not having their feeds update with new postings as recently as Sunday morning. This coupled with others getting follow/likes blocks as well despite being standard users.
The feed update issues and just general fatigue of it not working right now is probably the primary culprit for your numbers.
