If you sub for sub, you need to stop, right now. It hurts your channel. For one, people who do sub for sub, have no interest in your content, they just want a sub back. When you upload a video, YouTube shows it to your subscribers, if no one watches, YouTube will assume they don't care about it and bury your videos.
Sub for sub is also against YouTube's rules, so they will ban you once they catch wind. If you ask me, sub for sub is lazy, you don't want to put in the time to make videos like everyone else. And that's cheating, and cheaters never win. So if you want to cheat, and sub for sub, YouTube will punish you. It falls under the same belt as being on a job and making someone do your work for you. The person can show you how to do the job for visual learners, but if you expect a free pass, I'm sorry buddy. It doesn't work like that.
So why risk getting banned when you can just making videos?
