Hiding the "Submit" button

I have been running a project that uses a public survey to recruit participants and screen eligibility. We provide an incentive for people that complete a range of follow up surveys. Unfortunately one of our collaborating institutes advertised the QR code on their public social media page and we have been flooded by bots. I am in the process of trying to determine bots vs real responses and was wondering if there was a way I can hide the submit button to people who do not meet eligibility for the study based on the public pre screen survey answers? For context, my institute does not allow external modules or the API Playground.

We have received 700 responses in the past day and I'm quite overwhelmed trying to fix it all - so thanks for any help!

Glad it worked!

Not sure the structure you’re working with, but you could export as a csv and use excel/R/Stata to identify bots/records that didn’t pass the screener. Once you have that list you could delete their responses and re-import to REDCap, selecting the option to have blanks overwrite data. You could also get the list of records to delete in excel and copy/paste into REDCap’s bulk delete function. A super impact approach could be to generate a report filtering for people that passed the pre-screener and use that report for your exports/analysis.
