@PhillyD not to add to your paranoia about yt suppression but...
I have watched you daily for 3 years. Yesterday your video did not appear in recommended. Had to go to find it in the sub box.
YouTube seem to be promoting artificially grown channels i.e using sub and view bots, during one of my searches one of these channels came up as an add. I mentioned it to Team YouTube here on the twitters and got the same boring generic, copy and pasted response 1/2
