That is exactly our opinion also. We understand that some think it is a bit scary letting people test any site they want, but the fact is that anyone with a DSL connection at home can choose any site they want out there and put a lot more load on it using their home PC, than we allow anonymous users to do with our service.

We want the service to be really user-friendly and easy to get started with, and think we have reached a fairly good level of compromise where security is "good enough" without sacrificing usability.

What we could, and should do, however, is be more informative about all the security measures we have taken to prevent abuse. Because we have put a lot of man-hours into that lately, and we will continue to build more, hopefully non-intrusive, security measures all the time to try and make the service unattractive to would-be abusers.
