It wasn't one guy that made me shut it down, it's the pattern of use that typically comes with offering a service like this. At the time, it wasn't my primary focus, just a one off, "What would happen if I did this?" type of experiment.
Yes, I knew that there could be abuse, but I didn't know how the abuse would come. As I said, I learned, it cost me very little to do.
> What insight does that give?
For one, how do you maintain a service that actually has traffic. At the time I had very little experience with mass amounts of users. You can build personal websites all day long and still never know what it is like to handle high levels of traffic.
Additionally, given the type of content I received on the service, how could I handle the patterns of use better and encourage the sharing I wanted from users? Given the type of content I got very clear patterns developed that if I wanted to expand I could have.
> Surely you knew there is at least one bad guy using the internets before the experiment?
Yea, there are people with ill intent on the internet and they are constantly attempting to break into my servers as we speak. Why would I use that as a reason to not offer something online? This reason alone, shouldn't be a deterrent.
