I'm gonna be honest. The fact that anyone on this forum uses AdBlock infuriates me.
This is a site about promoting and helping to support YouTubers, and here you are advocating software that robs them of income. It's a sad state of affairs when watching an ad for a few seconds, which actually helps these people make a living doing the very thing you're watching them do, is so difficult that you have to install software to block it. You might as well ask why you'd bother buying albums and movies when BitTorrent is free?
I have few "rules" in my life, but a big one is "what would happen if everyone did what I'm doing?" In this case, what would happen if everyone went "oh I'll just install Adblock"? The answer: either the concept of a "professional YouTuber" would vanish and ALL content would revert to being lower-quality done by people who still have to work another full time job, OR YouTube would simply remove ads in favor of a paywall ENTIRELY.
Ads KEEP YOUTUBE ALIVE. They're not spam, they're not there to intrude upon your life. Without them, there is no YouTube, and with that everyone's dream of doing YouTube full time evaporates.
Good job.
