Hi,

It is just WordPress theme.

CityTours theme has not feature to prevent spam registration.

I think you can use any plugins to prevent spam registration and increase website speed.

Best Regards,

Hi Team

We are experiencing so many spam registrations (via contact form) after the theme has been applied. 

Also the speed of our website has drastically reduced.

Kindly resolve these two issues

Thanks and kind Regards
