Spam comments with garbage links

I keep getting more and more garbage comments on this blog. Comments are moderated. Therefore they don't really make it unless I manually approve.

Now the spammers are getting creative. They post some positive generic praise before positing their garbage link. In fact, it is most often just a bot that crawls the web and posts random comments. Sometimes it is a crowdsourced effort. Each comments receives a few cents. The generic praise is just to sound relevant and trick the moderator to approve the spam. It also tries to make random readers to click the link once the spam comment is approved (often, by mistake).

Sharing a few garbage comments my blog posts have received below, after removing the link (why would I post the garbage link myself? lol).

[GARBAGE-LINK] GARBAGE-COMPANY provides real estate solutions to homeowners that want to sell fast without paying any extra realtor fees.

^^ Some spams at least try to praise my post in a generic manner before throwing their irrelevant garbage link. This comment comes directly to elaborate its garbage company following the garbage link.
