For whatever reason, YouTube has been randomly removing ACTIVE subscribers of mine for the past month or so. I've had viewers personally alert me via Twitter and Facebook that they were unsubscribed for no reason at all. This is a known issue that needs to be resolved ASAP. It's not only happening to me, either. Check out Chris Pirillo or Ty Moss, and they'll confirm the issue. It's a bug that should've been fixed weeks ago.
I take great pride in my content. To see my subscribers count drop by the hour, it's just mind-boggling. In my 5+ years of being an active content creator on YouTube, this is my first time witnessing such an occurrence. Please, I beg of you, YouTube — resolve this issue. I've continuously reached out via Twitter, Facebook and Google+, but talking to an actual person seems next to impossible.
If this issue is affecting your channel, please spread the word! I would greatly appreciate it.
