I just deleted another comment that seemed reasonable but was attached to an advertisement.

Here’s a note to all of you advertisers out there: If you want to leave a comment on this site, please do so without the link to your website on search engine optimization or whatever. Or else it will get deleted. Which means you were wasting your time in writing the comment.

I want your comments and I don’t want you to waste your time. So please just stop already with the links, and we’ll both be happier.

P.S. Don’t worry, you’re still not as bad as the journal Nature (see the P.S. here).
