Correction:
“I haven’t found bots on TS. I’ve found real people. I always check their profile page before following them back.”
So do I. If they look interesting and have some decent content, I’ll follow them. And I try not to follow back people who are obviously just following everyone they see out there in hopes that they get lots of people to follow them. A good hint is when they have fewer than 500 followers and are following multiple thousands and accumulating them just as fast as they can. You are just a number to such people.
