Links are only one factor that gets your comment more likely to be deleted or shadowbanned by YouTube automod (in addition to channel owners' settings for filtering). It's a well known issue for 1-2 years afaik

See the discussion in the following video for example ("YouTube deletes your comments #Shorts").

Contrary to what rasz said, even if you see your comment in the Comments History page, if your comments are shadowbanned, you see your own comments in History but nobody else can see them.

You can use a Piped page like above to check if your comment is displayed for others to see. Even the incognito mode doesn't work.

It's kind of futile to try to do any important discussion in YouTube comments
