"To be honest I dont see the point in questioning it!"
Because you don't know how to get past the page with the reCAPTCHA ("no idea how to solve this one")? Because the effort required to get past it is greater than accessing data via a sensible mechanism? As interesting as you claim to find this you've offered none of your insights as to how to achieve this.
If you know a lot of perl as you claim you could offer to work with the sysadmin to develop a sensible mechanism/API to allow yourself and others to get the data you need. For all I or anybody else knows you could just be looking to bypass a registration/submission page to spam some forum, since this method of challenge/response attempts to ensure that end user is human, and not a script.
