Duplicate Leads coming from form fills

Hi All

We have duplicate leads coming in from the web forms. We found a lead in the system where 8 duplicate records were created in Marketo from the same form, and same details. The time-stamp on all the records is almost the same. When I tested at my end, the form worked fine and no duplicates were created. Any idea how this might have happened?

If the form is reposted very rapidly in a short timeframe (as you say, the timestamp is almost the same) this can happen because the inserts do not see the existing records yet, so do not perform a merge.

@sanfordwhiteman Is there a way to prevent this from happening? I have something similar from records created back in December 2022 (same create date, same activity log, same fields/values but two different records). Understand that if I had caught this in real time, I should be able to wait for Marketo to process and auto-fix the dupe but this created duplicate records a few times now. Is it something about how the form is embedded onto the page?

IMO in the ideal circumstances, the chances of this happening are pretty slim as there's always at least a few seconds of delay b/w the legit human form submissions from the same person, which in most cases should be sufficient for the previous form-post to get committed in the Marketo DB. I suspect these form fills could be from bots, and I'd suggest setting up the CAPTCHA on your form if you're seeing too many of such form fills.
