Don't listen to these people they have no fucking clue. The reason your engagement drops is that instajews reduce your appearance in the explore tab. Ill give you a rough example: before drop a photo contain 2K likes may have gotten 1200 likes from your followers and 800 likes from non followers. The only way non followers would have seen your photo was tag or explore tab. After drop. E.g you increase followers but you same example may give you 1200 likes from followers and only 200 likes from non-followers.
So in order for you to reach that total of 2K likes you will need say 1800 to come from folliwers and 200 from non followers.
Now you think to yourself how do you go from 1000 follower likes to 1800 follower likes? Only one answer. More followers.
So if 50K gave you 2K then chances are after engagement hit, 80K is needed to hit that same mark.
I don't give a flying fuck what everybody says I AM RIGHT. And a big thank you to the people who support me through PM etc. we are laughing and gaining followers like fucking machines while other people give out incorrect information and shoot me down.
