I have a few forms up on our website. The "Lead Source" field is hidden and auto populated with "Web Research" as the value.
Over the weekend I had a lead come from one of my forms with the Source value as "Advertisement." The lead was bogus and SPAM. But I do not understand how my Lead Source value was changed.
I've gone and checked all the source code of the forms and nothing seems to be wrong.
Has anyone seen this before? Any ideas?
