It would be wonderful if every link from this forum over the years still worked, but the fact is that content comes and goes on hosting sites like PH, XVids, etc.
We lost a ton of great hair content a few years ago when PH cracked down on unverified accounts.
If you see something that might look good but isn't at the original link anymore, maybe you can find it somewhere else. Google it. Or, ask here if anyone still has that content on their hard drive or their cloud account and would be willing to share.
