The reason behind people buying so many acc's is the following: YouTube have a limit of 2 comments every 10 minutes. If you exceed that limit you have to fill in a captcha. Most Youtube Comment Spammers can't break captchas, so they have to change the account every 2 comments Hence the reason for so many accounts. With 50 accounts you can spam 100 posts/videos.
lol yeah actually the main reason behind this is implementation of Phone Verfication and mass Deactivation of spammy accounts so as a result you need more accounts lol
I need some accounts too.... 50, 100... whatever. pm me people. Also, who can reccomend a good piece of comment/rate software? They all suck from what I've seen.
