These kinds of threads appear from time to time and I am tired of answering them. I did get banned for buying views. first the video was removed, then the account was terminated, but everything was done within a day so I didn`t really have time to change anything. Truth be told I did buy subs and likes on that account too, not just views. But it is something to think about
Are you certain you had the channel terminated for buying views? Correlation doesn't mean causation. Some quick considerations off the top of my head:
Did the video content violate the community guidelines in any way? Did you use any blackhat related keywords in your title, description, or tags? Did you repeat your main keyword/s in the description multiple times? List tags in your description? Promote any questionable links in description or comment? Was the video completely original or did you use pieces from other YouTube videos?
For the views that possibly got you banned, how many are we talking? What was the delivery speed, geo locations of viewers, traffic sources, devices, average retention, etc.? Did the seller specify any kind of guarantee (usually 30 day, 60 day, lifetime no drop, or no refill/guarantee)? Was monetization turned on or off on the video while the views were being added? Did you buy the views while video was unlisted and if so, how many? Did you have any real subscribers that would legitimately watch your videos or was it a fresh or low sub/view channel? When was the channel created? Did you upload multiple videos at once or just the one?
What other services did you purchase alongside the views? You specified likes and subscribers; what was the view to like ratio, speed, etc.? How many subscribers, did they drop after delivery and if so how quickly were you losing them? Did seller offer any guarantees for the likes or subs (no refill, lifetime guarantee, etc.)? What about dislikes, comments, shares, playlists, embeds, etc. or was it just likes and views to the video?
Those are hypothetical questions that I would ask if someone wanted advice on why the services they bought got them banned (don't actually answer them here, they are just things to consider in the future. Someone might stumble across this post and realize their strategy is missing something, lol). The reality is, most bans are from keyword stuffing titles and descriptions, using other peoples content in their videos, mass uploading, etc. It can be bad views specifically that get you banned but it's relatively easy to bypass those issues by using generally regarded 'best practices'.
