Thats not true... this is still working but dont go live with such a big amount like OP with 50k views.. Go in with 5-10k ... But the important Part is the quality of the Views .. Since YT changed everything like local ranking and fight against Views seller you need real views .... I dont know whats the quality from OP Service but retention from 1.50 - 3min doesnt matter when the views dont come from residental ips and yt accounts with history .... Everyone can embed a video on twitter and use a bot with proxies to send this views but this time is over now

Quality over quantity .. And you need constant views and engagements without spikes or stops and thats what the most seller dont have .. For Example you buy 50 k views the seller send this views in 8 hrs and then the traffic stop --> after 12-24 hrs video ghosted . Now you think there are sellers out with dripfeed option ? I tried many services and let me tell you something : its not dripfeed when the seller send you 20k per day in 4hrs --> traffic stop --> next day 20k in 4 hrs

this is a example of a good boosted Video this Video rank in a very high comp . Niche for weeks now in the top 2 and now the bad example --> i hope you can understand this now
