He is mighty happy with that ban button though.
It's the whole thing of being a fan and supporter then they step on your face for no reason, that kind of pisses you off.
I can't speak on behalf of Louis, but I can certainly speak as a content producer with a large audience.
You were not banned for "no reason" and surely you must know that (and IIRC you've admitted you know that).
When you get literally thousands of people per day commenting about your every word, or often things you
didn't say or didn't imply, much of it constructive feedback, but because it's Youtube, much of it just flat out abuse and trolling and what-not, it is almost impossible not the start banning people who ruin your daily experience.
It takes a very special and rare content prouder to be able to mentally survive the relentless onslaught of comments without having to resort to banning.
Now you can argue over the "trigger level" for banning all you want, but to do so is a mistake and failing to understand the position content producers are in every day they chose to read the comments and interact with their audience.
