Does the website get banned from Google or is there any penalty if you got a fake PR? And for a fake PR site how to clean the cached links and pages from Google? Thanks
A fake Pagerank of 7 could be done by a 301 or 302 redirect that points site A (PR0) to site B (PR7). The next Google PR update will make site A a PR7 site.
No, you will not get banned from Google but in next PR update your original PR would replace your fake PR.
