Check PBN links with or without google webmaster tools?

Hello everyone,

This is my first thread here and I have a question. I recently bought PBN links from someone and I've heard that sites such as Ahrefs and Majestic won't show them since PBN are "my secret sauce" and so they will black the crawlers from SEO sites so my competitors can't see them.

Is this true? And if yes, I'm currently ranking for a blackhat niche and I've also heard that it's bad using google webmaster's tool for such niches, so if the links don't show up on SEO sites and I can't use google webmaster tools what should I do?
Hope to get some answers

By verifying a site with google webmasters tools all you are doing is verifying you own/control the site.
Google already know about those links it will show you they just want to be sure you have the right to see them.

That said. 1 site per GWMT account always to stop them linking your stuff together

You want a way of verifying if you got what you paid for?

If link checkers are blocked, you can either add GWT (which wont show all the links for sure), or verify via a report. Other than that, the only thing left is if you see a rank boost or not. Not much else you can do.
