Getting immediate suspensions upon using accounts

I have made 2 account creators, one simulating the website's http requests, and one simulating the Android device. But regardless of the quality of the IP's I use, all created accounts eventually get suspended if I use them partially. More, since 2 days the moment I use an account it suspends, whether I use website requests or Android requests doesn't even matter. They just suspend the moment I try to follow/like/pin/repin... Anyone have any idea what's going on, and maybe what it takes to make the accounts last better?

On my new accounts, I can safely like, repin, and image upload.

Do not, I repeat, DO NOT follow anyone on a new account.

I wonder how usual users of this service cope with it!
