While browsing through the local craigslist ads, I realized there might be a need for a centralized database where people could report addresses that are involved in or associated with scams.

Is there such a thing already???
If not, I really think there is a market for such a service.

Let's say you are being presented with ridiculous offers that not only sound too good to be true but are also shady as f**k.
Wouldn't it be nice to be able to look that address up into a registry where other people have previously reported scams???

Not sure how feasible this would turn out to be, considering the amount of addresses generated every second... BUT... I don't think it could hurt either...
Most scammers are probably lazy and wouldn't think of switching addresses until such a service would become popular and/or adopted by bigger players (e.g exchanges)

That could really help a lot of gullible people who otherwise would fall prey to such scams.
I would personally use such a service if there was one

Let me know what you think...
