He would need to review each server for over a week, before he can make a video about it.
Sometimes servers aren't fun once you start, you meet people guilds, fortress, and enjoy the heart of the game, not just by logging in and seeing a few globals.
You can't judge a book by it's cover, you need to read the whole book [ take a full in-depth look inside the game ] before you can do a full judgement that is correct and valid.
As well as he can use hatred towards server owners, or just exclude particular people who he had a grudge with in the past, and bring it to the presence, and judge their servers badly, just because he doesn't get along well with the present server owner.
It's honestly a nice idea, but it's also a failure idea as well, and most people will figure this out along the journey.
And that's just my opinion, others can have different opinions.
