Hi,
I’m hoping someone can help me resolve a worrying problem.
Over the last few weeks we have been hit by spam activity which is adding a large number fake email addresses to our audience. It looks like they are using our Newsletter sign up facility as access. The format of the spam record’s name is always 0ykAAKrjU2 9Bygq83ijO. A 10 character ‘first name’ and a 10 character ‘last name’. Email domains are very varied with no clear pattern.
I’ve managed to remove lots of the spam records but approx 200 are being added per day. How do I block them?
