YouTube subscriptions gone

Has anyone else had their youtube subscriptions deleted ?

Got on to have a look this afternoon and only 3 left of about 25 subs. Chris at Vogus mentioned this happening a couple of weeks` ago and all was ok for me back then ,but now his channel, Pioneer Pauly ,Tassie boys, abandoned mines and a heap of others like Ken Block and Aust film archives, dashcam owners and many others have been deleted from my subs list. Dashcam owners sent me a notification only this morning ,so this has happened today.

I can`t find out why this has happened. Any ideas anyone , please ?

I am going to have to re-sub to them all .

I subbed to Nenad this morning and his channel is still there.

Thanks, 7.62marksman.

They haven`t sent me one of those ,yet. My google account is linked to youtube and i can`t see my history or subs without logging in.
I have just finished going through my youtube history and re- subbed to most of them ,but not all. No idea why , but the 3 abandoned mines channels didn`t turn up in my history. I had to look up the cinnabar mine video to find them all again.

Funny wording about bad actors , here . Never knew there were good actors on youtube.
