Alright, so I have been doing a ton of spamming on youtube comments lately and I have run into a bit of a problem. Most of the time I run 150 accounts through 100-150 URLs spamming 22 comments but last night I compiled a list of 950 URLs and typed up 88 different comments to post. I ran the 150 accounts through all 950 URLs randomly posting the 88 different comments. Today when I checked the URLs, there was a ratio of about 1 out of every 10 videos had the comment posted on them. No comments marked as spam or anything. Now, I have been using these 150 accounts for a while and there are a few other people that use them to spam and flag and so on also. Could the comments just be completely blocked based on too many flags for spam? Or why would they not be showing up? I'm about to buy 1k youtube accounts and just keep them constantly posting on the URLs. Can anyone fill me in on how the comment spam filter works? I need to know the best way to spam URLs with multiple accounts without having them marked as spam. Thanks!
