I know, I know... always expired domains and PBNs, it never seems to end today I have a question that was not discussed yet as far as I can see: I have an interesting opportunity to buy some decent domains with clean backlink profile. They have been legit sites in the past, no spam or any no-gos whatsoever. BUT: They have been parked for the last 2-4 years. Would you still buy them for PBN purposes or do you see any risk? Does google like domains which were parked quite a long time?
