My Observation,
- Initially, I choose to go with free subscriptions where they ask you to 'Subscribe' and 'Like' random Youtube channels.
- When you successfully subscribe to those random Youtube Channels. I went back to review the list of channels that I had subscribed it on my Youtube history
- This is where is shocking part for me, I noticed most of that I had subscribed to those were REMOVED from my subscription list.
- I don't know how did they do that, I wanted to be loyal if I am getting free subscribers in return I wanted to keep them in my subscription, but no these guys have done something nasty that is causing me to remove a genuine subscriber like me forcefully. I recommend you retry my observation to confirm their nasty setup. Hope It clarifies your concern of you are losing those subscribers from your channel.
