Listen, I really don't care about subscribing to many channels, only those I find truly fascinating and/or inspiring. Just because you subscribe to my channel, doesn't mean I am going to subscribe to your channel. And if you add me as a friend, don't constantly send me your videos, chances are I am not going to check them out. In fact I am certain I am not going to check them out. I will let you add me as a friend but so long as you don't spam me with your videos. As soon as I notice you spamming me with videos, you will be blocked.
