Ask HN: I've been collecting Webform-spam for a year - what could I use it for?

Ok, this will sound stupid.

I've always noticed how much spam every single web-form you make tends to get if you don't implement a captcha or something like that. So I started recording some of that spam through a completely open web form

Now I have 729k entries and the DB is growing faster and faster. Does HN have any idea what that "data" can be used for?
