Haha, It wouldn't. Invalid reports are ignored by registrars. Nice try though
Are you just burgening registrars with complaints? I fail to see how your tool can not be used for sending mass complaints out of which 10% or less could be valid.
I don't understand your point about the tool being abused for mass complaints. We do have a captcha implemented with the form. If someone wants to spam a domain registrar, they can also spam from their email accounts. I don't see how we enable mass spam directly.
