Selling likes/followers question

Hello,

Thinking of buying some bulk accounts that I will be using to sell likes/followers for social media (Instagram/Twitter) etc, anybody knows a tool that can help you manage such a high number of accounts?
Or maybe an website platform that you can buy as done for you service for this?

Thank you.

I think it won't be advisable to use third party tools for that cos these apps frown at it and you might get your accounts flagged , but that aside there are alot of SMM panels you can use that sell like and followers and all that stuff , check the SMM forum
