It probably fake followers so it's useless. I also have 2 twitter accounts with 50k each and 1 with almost 200k, all not affective as it is bot followers.
Maybe some of his followers are fake i wonder what is the average percent if he audit his twitter. And his twitter is still useless even it is having plenty of followers and only few are real.
I think fake. 240k followers are a huge figure with ordinary people.
