With this app you can easily lock your shop against unwanted registrations: Simply write the e-mail addresses that should not register one below the other and save the settings. Already no customer accounts can be created for the e-mail addresses concerned. 

You can do the same with names and company names – just enter names/company names in the app settings and the customers concerned will be excluded from registration.  

What if there are many similar names or addresses from the same domain? Then simply block the whole area! Just enter “.*@example.com” in the emails and nobody else can register with an @example.com address. With the names you can enter “Mar.*” analogously, and neither Mark, nor Marc, Marius nor Marcel will be able to register in your shop. 

The system uses so called regular expressions, so other combinations can be excluded, up to whole top-level domains: Enter “.*@.*.ru” and nobody can register with an e-mail address from Russia. 

However, this system is very powerful and must be used with care: An entry “E.*” in the field “Company” prevents the registration of all company names beginning with the letter E.
