I'm very picky about who I follow and really try hard to avoid following impersonators or bots and one heuristic I would like to use is "follows of my follows" but I have not yet come across any client that would filter the followers by my own follows or at least put them first and highlight them. Some clients sort serach results by followers but fullowers is such a flawed metric unless those followers are my own hand-picked follows.

How do the more paranoid among you decide who to follow?
