I'm trying to find out where a few leads are coming into our system. On 10/31 and 11/1 there were a handful of leads that look like they are junk leads (we sell healthcare, these leads are from Walt Disney World and Disney Consumer blah). In the grand scheme of things, this is not a large issue - it is not effecting other processes - but from a trackability and data cleanliness standpoint, I'm pulling my hair out.
We have a marketing automation tool which we use to build landing pages and website forms which are tracked by lead source and lead source detail. These leads appear to have information filled out that we aren't even asking for on any of our web forms.
Because I am the admin, any automated process (website fills, etc) show in Salesforce as created by me. There seems to be a rogue form or process I am unable to locate and figure out where these leads were created. Any ideas of how I can locate more information? These leads do not show up in our marketing automation database, which in order to fill out a form they would at least have activity associated to it?
Anyone have any words of wisdom for how I might find where these came from? It's totally puzzling.

Yes. We do have lead source and lead source detail as hidden fields associated to all our webforms (which are built through our marketing automation tool). These particular rogue leads do not have any lead sources or lead source details associated to them. It's incredibly puzzling.
