My YouTube account is from 2006 and it's verified. I don't believe I'd have any comments deleted automatically. I'm not saying it can't happen, I just have never experienced this before.

Plus, this comment has been nuked and it's been there for a while.

I think they update the topics and filters occasionally. I tried to rephrase something 5 different ways on a video. I eventually had to use DM on twitter to reach the content creator. It was on a video by Matthew Kratter.

Words that were an issue:
Damus
npub
Nostr
Go to the video and see how I was asked about Nostr.
I COULD NOT MAKE A COMMENT GO THROUGH.
I instead made a comment telling him to check his DMs (on twitter).
He only follows 9 people on Nostr. I am 1, probably because I gave him some information for joining.
I believe he would not delete my comments on YT. I also think he is busy, and generally wouldn’t just go check twitter DMs because someone told him to. He wanted the information. So why couldn’t I get it to stick?
I can only assume YT was playing internet police.
#[6] check my receipts
Now go look at his only note on nostr
