YouTube likes to ban small time YouTube channels and seem to never go after the bigger ones. This is something that's happened quite a bit over the years. They will give you strikes much easier and ban you but a big time YouTube channel might not receive the same. I know several people who had between 1,000-5,000 subscribers and have been banned before just because they make comments a lot on other channels. It's quite a shame. These people I know start their channel over and have been doing fine since.
