Most dropped domains with
PR are fake. People can easily fake a PR8 domain using redirect to a real PR8. Also PR8 is very very rare so I would suspect it is fake.
You can use these sites to check fake
PR. The first site is the most reliable. The site will tell you if your domain is redirected from a different domain in which case it is a fake pagerank.
