I've got a site using FreeForm 3.1.4 which is having a bit of an issue where guests are creating their own collection by, presumably, manipulating the source before submitting the form. As you can see from the attached screenshot we have several "collections" the ones that should be there are prefixed by HGI. All forms on this site are using honee-pot.
Is there a way to prevent this from happening? Back in February I posted this to the Solspace support forums but it wasn't resolved.
All suggestions greatly appreciated.
