Couple of questions: 1. I bought a few domains for a PBN. I was checking them again after I'd bought them and realised one of them had a high moz spam rating (still has good DA / PA / TF / CT. Think the spam rating is like 8/17. So what should I do with this? Should I throw it in the newtork anyway for 'diversity' or maybe I could use it as a lower tier and point to some web 2.0s and then point them to top tier? Or just drop the whole domain? Could it have a negative effect? 2. On my main site I am targetting a lot of 'easy' longtails. Am I better pointing my pbn backlinks at the easier keywords or the harder ones? My idea is that if I target the tougher keywords that really need the PA, the increased DA should still have a good effect on the easier keywords? Or should I do it the other way around? Thanks!
