I was checking my referal traffic in Google Analytics this morning and I discovered referals from an unfamiliar URL.
On checking the URL I found...
A copy of my entire phpBB forum!
Only the header had been changed, to include a banner for an affiliate in my niche. Funnily enough, they'd left in my own affiliate ads elsewhere on the site.
I've filed a DCMA takedown notice with Google and the host.
I've never heard of this happening with forums before, but correct me if you've seen similar.
Presumably this incident is related to a warning I got from Hostgator last month about high CPU usage on my account. I found an IP address from the Philippines was mass downloading my forum. That was pretty serious as I nearly got my account closed . I solved it by blocking the particular IP in .htaccess (you can do this through cPanel).
Anyway, if there are any PHP programmers reading this, then I'd love to know how to block crawlers. Maybe you could keep a log of how many requests you're getting from a specific IP address in an hour and block high users. I know how to do this in ASP.NET, but don't know enough PHP to be able to make a phpBB mod for it.
