Please, when buying views, question the seller who is selling the views. Ask for the demographics, retention (and if it's a static number or a dynamic range), speed and devices. Don't end up with a shitty reseller who doesn't know what they're talking about and tries to lure you in with "Black Friday discounts" even when it's not BF. I haven't had a video banned yet due to asking these questions from my seller. The key to buying views is to make it look like you aren't. So, if you're promoting something on YouTube and you are buying views, those are the key questions to ask.
