Hi, we have a situation where someone is creating several accounts (about 20 a day), they use an email address like cholse1111 then cholse1112 iterating the number each time. They only make it through the account creation (never through the payment screen). Their IP changes all the time, so we cannot block their IP. For now we are just going to to run a query that deletes all accounts that have an email like cholse####. It this something we should be concerned about?
There is nothing serious. It seems to be a bot which just submits signup form. Try to enable reCaptcha on signup form, this should help to prevent such signups.
