3rd Party Captcha Solutions to counter aggressive bots?

Hi,

 

We are currently under attack by some pretty aggressive bots that come to our Marketo forms via Google Ads. I have implemented reCaptcha V3 integration, have Smart Campaigns running to recognize and delete suspicious leads, and am also using ClickCease fraud prevention for our Google ads account.

 

The bad leads keep on coming and I am going nuts! Have any of you implemented a more robust 3rd party Captcha solution to try to thwart these bad ole bots? Could you please share details of the solution and how it is implemented? I am trying to find something that integrates with Marketo forms but nothing is jumping out at me. 

 

Thanks so much!

@abaummidaxo ,

remember - reCaptcha doesn't stop the leads coming in.  It just assigns them a confidence level of human vs bot.  It's up to you do something with them (e.g. delete if confidence is below <x>, refer to human for review if confidence between <x> and <y>, retain if above <y>).

 

Cheers

Jo

Following this thread as I am currently implementing reCAPTCHA v3 and would like to hear about any other solutions.    

We've also had some bots from Google Ads.  Many of the responses all have "@mailinator.com" domain. Mailinator is an email/SMS workflow testing service so not sure if we got caught up in some workflow or if its spoofing their domain.

You don’t really need to worry about other solutions before vetting reCAPTCHA, which is still the standard.

 

mailinator.com, while a legitimate service, is considered a disposable email domain. It’s used by spammers because email addresses will appear to exist, but don’t correspond to humans.
