Now check how many times he links to his blog in comments.

Actually, here, I'll do it for you: He has made 13209 comments in total, and 1422 of those contain a link to his blog[0]. An objectively ridiculous number, and anyone else would've likely been banned or at least told off for self-promotion long before reaching that number.

I like being able to follow tangents and related topics outside the main comment thread so generally I appreciate when people do that via a link along with some context.

But this isn't my site and I don't get to pick the rules.
