I have recently come across videos that have blown up to 2-4 million views in 1-3 days. They are both from YouTube channels I have since long suspected are doing something fishy. If you check the comment section of the videos in question the uploader has made some comment and pinned it. This comment has almost 20 000 likes... and the comments to this comment made by other people have 2-3000 likes. Like... seriously? 3000 people would like someone replying "hello" to someones comment? And 20k likes on the main comment? That is IMPOSSIBLE! Does anyone know what kind of service lets you buy likes on your comments? Because that has to be what he is doing I can't see any other way.
