I have a friend who is a best-selling author, and her threads account was being heavily throttled (hundreds of likes a few months ago, fewer than ten now) -- it was suggested that it's because she is posting links away from Meta properties, and the way around it was this "link in the comments" tactic.

So it's not necessarily clickbait -- seems to be also an evolved workaround to fight throttling. :-/
