Signup which looks like successful but blackholed is user hostile. Majority of web form spammer don’t even try to evade filtering - why bother when there are many web forms without validation. All signup spam I’ve ever seen in email was sent via forms which allows to enter longish text in the name field with ether url or email address or phone number. Reasonable validation of user entered fields used in signup emails should stop 99% of such spam.

I only do it for things which are clearly not valid users.
