Hi Asif (@cryptex_vinci)
many thanks for your reply. I am familiar with the blacklisting process, but this id is submitting variations, e.g. r.o.l.o.+, rolop.+, ro.l.opo.+ – so there is an enormous number of permutations that would need to be added, and of course, email addresses can be created at the drop of a hat! I may have been able to associate an IP address, and have blocked the IP range. Since then I have had no issues – but my primary concern is that if a user registration can suddenly appear with no intervention, fully formed and approved, then that is a concern. Can you advise how that may have occurred, and how we might take actions to prevent it? Thanks
