What if someone brought 3-4 domain names, built up thousands of BAD/CHEAP backlinks for the domain names and then weponised them by permanatly redirecting them to a target website?
I know of a link network that is still hosted, but deindexed by Google. It was used prior to its Google deindexing for genuine link building of course. Post-deindexing, I see posts still being built to it. I doubt the link builders are that dumb to not realise those domains are deindexed by Google - it looks like these are being used for negative purposes. I know that Google do visit deindexed domains, so it does make you wonder.
