I've boosted views on dozens of videos in the past, some as much as 100k in a day's period, and they've never gotten shut down. Now it seems to be different. I purchased YT views from 2 different sources (20k high retention, 45k low retention), and I had a great original video in a low competition niche to send the views to. After sending the views, the video got taken down in 48 hours later. In the message that says my video got taken down, it also said that I will be further monitored for suspicious activity. I don't want to lose my Youtube account (I've put a lot of work into it), but I do want to use the video specifically on this account (because it matches the content of other videos on the account). Has anyone here had further difficulty boosting videos after having one previously taken down? The reviews on my view sources are completely positive and indicate that nobody else had their video's removed due to their traffic - is it possible that attempting to boost using multiple services was what tipped Youtube off? It seemed both of my sources were over-delivering - I had 40k views and 330 Likes in only a few days. Or are we getting to the point where you can't boost videos anymore without using extreme caution? Make no mistake, I'm going to experiment - but a few tips from a kind soul who is privvy to YT's detection methods could save me a lot of time and money.
