I was changed the program, but when I to update , that come back sooooon .
I was tested it's easy , just to check the previous page domain , if this domain is different of this web domain , just die it. Can we?
I don't like when I update and the problem still stand there .

Looks like the suggestion here is to add a basic anti-spam protection based on domain verification.

1. This can be done in a plugin, you don't have to hack core for that.
2. This sounds like plugin territory to me. See also #27682.

I agree with @SergeyBiryukov, your specific use-case would be best added as a plugin.
