At the beginning of October I was starting to get referral spam so I implemented a blacklist to help remove anything that wasn't a true referrer. Well over a month on and I now have 10 times the amount of referral spam. It's not just the same stuff either - they are really clever with their domain names containing none of the keywords I'd previously picked. This means I have to login each day, checks the logs and add a new set of keywords to the list.

So I've coded up yet another change. This time I've inverted the functionality to only show referrers that I have configured. The code turns out to be cleaner and the site is far less maintenance for me so hopefully this should solve my problems for a while.

[Edit: I've sent the code to Omar so this should make it into the 1.7 release]
