Suspicious twitter account


is there someone here with solid knowledge on twitters security systems? I’ve found an account which is really suspicious. They only have around 60 followers and 90% of them are verified celebrity accounts. But their first few followers look like bots. The person behind that account also runs 4 other accounts which are also followed by a bunch of celebrities. I’ve seen them make requests for follows and the celebrities always follow them back, like immediately.
So basically my question is, is it possible to hack accounts to force them to follow you?
(also, I’m aware of how crazy and obsessive this question seems, but trust me I’m just curious on this one)
