Has anyone experienced this? We're doing form testing and are finding that once our testers submit a bunch of forms to Marketo, even from different urls, even after clearing caches, are getting blocked from submitting to Marketo. Once we give the url to a new tester, the form submits fine. And after 24 hours or so, we're finding that the old tester can submit a set of forms again for a little while, until they get blocked again.
Looking for any thoughts or whether anyone else has seen this. I know they are implementing bot stuff in the next release, but haven't yet....
We're using a custom LP domain (not Marketo landing page domains) and Marketo Forms 2.0 JS API.
When we test form embeds without methods (methods are addHiddenFields, onValidate, onSuccess), we don't have a repeat submission issue. But when we had the methods, we immediately see the repeat issue.
