Honestly, it's not worth it. I've NEVER been into it personally and I'd imagine it's much more sad to have 500 subs but around 50 views on your videos as opposed to 50 subs with 50 views. So, I would definitely recommend against trying to get into it because they are definitely not a real sub if you have to sub back.
P.S. Kudos to the amount of times I stopped being a lazy fool and typed out the word "subscriber."
