Hello,

I Receive a lot of spam registering users and even they are not from the Register page, How it can happend?

because i can see a lot of new spam users are registering when i have no visits even in Register page.

How i can resolve that and stop it?

I think Contact Form Limit Plugin is exactly for this situation.

Problem here is, that even you remove contact form, if you create post request (i.e. using Postman) to your site, it will still handle it. Bots are not browsing your site, they just cache forms to be able to send data to it.
