Our products work for 30 days before requiring the user to register. It's a crude (but reasonably effective) way of deterring piracy. At the end of the 30 days a dialog box pops up with a hyperlink. Clicking on the hyperlink takes the customer to our online web form where he can fill in his details (name / email address / order number etc) and we'll then send him his license.
Quite regularly (about once every 6 days) I receive a small batch of submissions that are always filled with garbage data. Invariably there are five submissions each time. I assume that someone must have written some kind of app to trawl the internet looking for web forms which it then submits using garbage data for some unknown reason. It's been happening for about 3 months now and is little more than an irritation. There are only ever 5 submissions, all within a few seconds of each other, once every six days - but if I was getting thousands of submissions per day it would be a major ballache!
Apart from the obvious (being an imbecile with too much time on his hands) what would motivate someone to write such an app - whose only purpose seems to be to irritate someone they don't even know? Is there some potential way that the author could gain from writing an app like that
