If you are advertising that you Sub4Sub on your channel. Do not have the Friend Lock enabled. I ran across a girl on YouTube that posted that she did sub4sub, but when she came across someone who had the Friend Lock enabled or approve comments enabled, She would block them and not subscribe. Her reason for blocking was she believed in free speech with people she wanted to become friends with. Can't say that I blame her. YouTube is all about making friends that will watch your videos.
So, keep your channel open. If you do not like a post on your channel, you can always delete it.
