Spam links, what to do?

Question

Fight against spam

Good day.
I maintain the site https://planeta-zarabotka.ru/and recently there was a huge spamming of links on "checktrust.ru" as much as 45%, I'm just horrified where such a percentage figure came from. The fact is that I have never traded links and there has been a plug-in with closing links for a long time, that is (rel="nofollow"), but according to "xtool.ru" everything is cool, even there is not a single circle.
Please help with this question, I am purely shocked why there is such spam, if there are not many external links, and if I traded links it would not be so insulting, but I never traded for you either ...

Remove all links in the js onclick by going through all the regular replacement content.
