Dude, I had my account deleted for something similar; in my case, it was an error in their algorithm.
Basically, I was making gameplay videos, and their algorithm flagged them in my dashboard as mine (100% match). I filed my usual strikes (since my content was constantly being stolen even though I left a warning in each video description that I didn't authorize its reproduction).
The thing is, the videos were NOT mine; they were almost identical, which confused even their algorithm. Because of this, I was accused of predatory behavior. I explained it to them, but as always, they didn't want to back down, nor did they bother to look into my case; they simply banned me.
When you're banned from YouTube, they track your IP, MAC address, your video card, everything. And when you try to post videos, they ban you again. The worst part is that AdSense gets blocked.
I honestly gave up, I didn't want to know anything more about it, but in your case, them banning you because of 2 fish is something that surpasses all limits of absurdity.
Good luck on your journey.
