@jl777 : Why do you have so many upvote bots?

This question is for Hive account@jl777 .

Seriously, why so many? What purpose do they serve?
They tend to swarm, but is that necessary? Are they necessary?

EDIT: I now realize that my post comes off as a complaint. I assure you that's not the case.
I'm a novice when it comes to this kind of thing, so I was hoping for an informative answer.

Thanks for chiming in. :)
