hey guys I found 3 decent domains with great backlinks in my niche the problem is, i notice in archive that they were used previously as a PBN. Anyway are these domains worth to buy? I need them only for a one time event promotion to rank them fast and then forget it. I don't see them in google when i type site:url as they are a bit old. Is there any way i can get them indexed again if they were penalized?
