I have a very authoritative site. Once I accepted for free a very good guest post (i rarely do that) and a month ago I noticed the guy was sending crappy backlinks from comments and stuff, despite me telling him not to do any shady shit that might compromise my site.
You know what I did? I deleted that post and reported his site on google for spam. He probably payed top notch money to a writer for that post, and some money on fivver for all that crappy links. And all he got in the end was a middle finger and possibly a google penalty. Keep that in mind before sending crappy links to authoritative sites that actually care about their backlinks
