I definitely didn't mean to say that you personally would abuse the resources, but the problem is that if the site is easy to use from scripts, then it is just a matter of time for some abusers to appear. Some are not even intentional, but send as many requests to the server as they can and then the service becomes unavailable for everyone. Limiting the rate of requests is a difficult problem to solve since you don't know how computationally heavy a given request is in advance.
