Since the end of August/start of September a number of websites have been under denial-of-service (DDoS) attack. The common theme among these websites is that they are run by volunteers trying to make the internet a better place, and reduce or create awareness about the threat of online criminal activity.
Here's a PC World article which has more details
Unfortunately as a result, FraudWatchers (www.fraudwatchers.org) have made the decision to remain permanently offline. This is a pretty big loss to the community, but there are other sites still around. Here is some sites recommended to me by a person who was heavily involved in FraudWatchers.
www.scamvictimsunited.com - good for all types of scams.
www.internet-love-scams.org - Highly recommended but solely focused onto love scams (for both the Russian and West African variants)
www.scamwarners.com - An offshoot from www.419eater.com, they have vast knowledge, mostly on advance fee fraud
www.autosec.de - Good for Romanian Escrow/Shipping scams
www.cattyshaq.com - Best for HYIP scams
www.thewholesaleforums.co.uk - Though this site isn't primarily a scam information site, it does have decent information concerning fake chinese electronics etc..

Fraudwatchers is now back
That's fanstastic news.
