Sup guys, I am new here and I want to ask just a quick question regarding building a PBN.

So far I've never really started making a PBN because I couldn't find any good domain to begin with.

But I found a Domain Agency in my little country that sells expired domains.
They have tons of domain that they sell and every week they update them. Usually every week I see around:
1-2 domain PR6
1-2 domains PR5
3-4 domains PR4
and so on.

And when I check these domains they are really good on Majestic, almost all have:
15CF
20TF

etc.. with a really clean backlink profile.

Problem is these domain once were used by universities, big companies etc and are old. For example for stats it says they had 10,000 back links 5 years ago but only 500-1,000 now and they are still pointing from high authority sites.

I purchased one over a year ago PR6 from a former University in Switzerland, domain was registered in 1999, used since 2009 then changed, I have it for over a year and it still holds it PR value, back links not much but still from authority sites.

And another problem, these are European domains, mostly .de and .fr

So what do you think are these domains worth it? They only cost 45EUR each.

And another interesting thing is I can write any whois data to any address and name I want They allow it.
