The scum of YouTube. Basically, they're robots disguised as your favorite YouTuber trying to get you to fall for some scam, where they steal your social security number, credit card information, bank account details, and other various things that criminals use to rob you. In other cases, they could also be getting you into a sketchy looking site that gives your computer an insane virus, one that can perhaps destroy your computer forever. Avoid at all costs.
