This post is for my own records.  March 7, 2012 - 8,123 subs. May 19, 2012 -  7,899 subs.  June 5, 2012, - 7,219 subs. (498 subs taken from me in one day alone).  Further, youtube is blocking others from subscribing to my channel.  How is this being done?  When users subscribe to ANY channel that has my channel featured on their channel, my channel does not appear in "also subscribe to these channels."  I've attached one exhibit, a screenshot I took from my buddy ZeroSixtyFive. I unsubbed his channel & then subbed back and saw my channel is missing & took a screenshot. It's the same with anyone who features my channel.
