I once used the similar strategy to hook into DC++ used for lan file sharing in our school. There was a chatroom game which had contest for unjumbling jumbled words. My app would inject into the DC++ messaging pipeline, read the unjumbled word and type back the correct answers.

It infuriated long time players whose score I beat in just a few days. It was fun :)
