Is it possible (or desirable) ever to block list sign-ups from a particular IP address? Nearly 100% of our fake subscriptions are coming from an IP in Ohio that is already noted in other online forums as being problematic for this behavior.
Simplest way would be to use deny from in your lists/.htaccess file
Deny From xx.xx.xx.xx
where the xx’s are change to the IP4 values from the suspect IP
If it’s IP6 values, then change all the xx’s to that really weird long collection of numbers, characters and puncuation.
Thank you, I will try that and see if it stops the spam subscriptions.
