This morning when I checked my videos, everything was ok, but after 4 hours all my videos were deleted. That's around 20-30 videos and all were ranked #1-5 on YouTube and Google. They somehow connected my accounts. I'm using VPN and proxies to upload the videos. Every time I log in into new account, I use CCleaner to deleted cookies and cache. I upload 1 video per account and use max 2 accounts per proxy. The only think that comes to my mind are the comments, because I use the same comments for all videos with little changes. Any ideas how YT connected my accounts? Edit: I'm also placing direct links to my site. Maybe that's the problem. Waiting for suggestions from more experienced members.
