reCAPTCHA Enterprise classifying everything as "Low Risk"

[dominikfeiler]

Hi everyone!

We've seen a sharp uptick in Spam sent via our Application which is behind reCAPTCHA v3 (non interactive) on about August 18th.
Since then (according to the reCAPTCHA metrics) nearly every interaction has been classified as "Low Risk".

In the graph below (showing 2 weeks) you can very clearly see a 'daily' ebb and flow of users as well as lower low-risk traffic on Weekends (August 12th and 13th).

However on the 18th that daily pattern very abruptly stopped and so did any "Medium" or "High" classifications.
Since then we've been getting complaints from customers that our application is sending out spam.
It looks like within the last 2 or 3 hours ratings seem to have finally come back.

I just wanted to put this out here and see if anyone else has seen a similar pattern during this time?

Here's another chart, this time going about a month back:

Cheers,
Dominik
