Subject: Inquiry About IP-Based Bot Detection and Increasing Block Duration in reCAPTCHA v3
Hello,
We operate a website built on Cafe24 that uses Google reCAPTCHA v3 for spam protection.
During normal website administration, we sometimes need to publish a large number of posts within a short period.
However, after multiple posts are submitted in succession, further submissions become blocked.
We have observed the following behavior:
-
When multiple posts are submitted from the same Wi-Fi network, posting eventually becomes blocked.
-
Switching to a different network, such as a mobile hotspot, temporarily allows posting again.
-
After continued posting on the new network, submissions become blocked again.
-
The duration of these restrictions appears to increase with repeated occurrences.
Cafe24 customer support has informed us that these restrictions are not caused by their own IP-blocking functionality.
We would like to clarify the following:
-
Does Google reCAPTCHA v3 evaluate repeated posting activity from the same IP address as potentially automated behavior?
-
Can such activity cause an IP address to receive a lower risk score or become temporarily restricted?
-
Does reCAPTCHA implement progressively longer restrictions for repeated suspicious activity?
-
Are there any documented thresholds or criteria related to posting frequency, IP reputation, or repeated requests?
-
Is there a recommended solution for legitimate website administrators who need to publish multiple posts in a short period?
We would appreciate any clarification regarding how reCAPTCHA handles this type of activity.
Thank you.
