My two cents about adblock: you're of course free to use it as often or as little as you like, but a lot of youtubers rely on ads for their income, and the way that youtube works, content producers are already getting a pretty awful deal before taking into account that about 40% of people use adblock, so they aren't getting paid for 40% of their videos' views, and whether or not people use adblock can make a big difference to them! Just food for thought.
