My follower drop drastically

So it all started out 3 days ago when i got back to the game of instagram , i bought a few fresh proxies throw it into followliker and automate it with all the picture ( including hashtag and description ) inside with an interval of 3 hrs each image being post. The problem is i have been doing this for a long time before i stop botting which give me an average of around 100 follower . However 3 days ago till now the follower i gain is only around 20~30+ each day . can anyone tell me what is going on ? And how could increase my follower as i seen people getting more follower than me each day . Thanks!
