 * I would like to protect my site from being spammed with loads of fake accounts
   by (among other used tools like google captcha) blocking temporary e-mail domains
   that could be used for creating fake e-mails within registration form.
 * UM/settings/access/other has the option of entering e-mail domains to be blocked
   and my question is:
 * I believe that we can add unlimited number of temporary e-mail domains but I 
   don’t know **are they going to slow down my site (or overload my shared hosting)
   if this list is too long.**
 * I want to add domains from the lists (links) bellow:
    [Temporary domain list 1](https://disposable-emails.github.io/)
   [Temporary domain list 2](https://gist.github.com/michenriksen/8710649)
 * Eventually, I would add even more temp domains if I find them.
 * Looking forward to your reply. Kind regards & thank you !

 * Hi [@justaniceguy](https://wordpress.org/support/users/justaniceguy/)
 * I also use the same domain lists and didn’t encounter any performance issues.
   Let’s see if others in the forum have encountered issues.

 * So, I have merged those two lists into one and removed duplicates ending up with
   about 3700+ temporary mail domains.
 * It seems that even such long list is it does not represent any problem with the
   site speed or shared hosting (server resources).
 * Therefore I am marking this thread as resolved.
 * Once again thank you for your time & help.
 * Looking forward to see the solution of other issue.
 * Cheers !
