Moved to Elsewhere

I'm guessing it's because before I got into mlp, I made crappy lets play videos on that channel that are now deleted since they were unfinished and i didn't wanna go back to it cause I lost interest and I found the videos terrible. In that period of doing them, I picked up 20 ish subs. I'm guessing one of those subs was an anti brony or something. Also, how do I still have subs since this is my first public video in like 2 years?

because people don't actually manage their sub lists, most people I know have like 70+ subscriptions.

I don't even have half as much and I only frequently follow like half my subscriptions.
