>First I got an email from Google saying that I was using 3rd party app outside of Play Store to go around Youtube ads
I absolutely do not believe this part, but I'm willing to dismiss this as confusion on the users end.
However, the rest of the comments by the user accurately describe how google account suspensions work. The same user had also created some rather reasonable issues before this one.
Agree with ryanlol's comment here next to mine on the rest. I'd really want more clarifications before I touch third party Youtube clients while logged in (which I want to be, for recommendations etc).
It seems really weird to me to assume that this is a troll, the other issues created by the user over a couple of weeks seem legit. I think this is just some slightly confused person trying to figure out why their account was suspended.
I get lots of legit bug reports from customers with strange inconsistencies like this mixed in, they definitely aren't trolling.
I don't think the emailed explanation exists, and I don't think confusion can explain why he'd say it exists, which leads me to conclude he's lying.
(And really, if such bans were genuinely a threat, more than one person would be complaining about it happening. Tons of people use youtube-dl and newpipe (including many youtube creators who do commentary on other youtube videos) and there's this single guy claiming to have been banned for it. It doesn't pass my sniff test.)
I just assume that these people are very confused and not good at english.
