This seems like an ego issue honestly. Like you feel like you are being taken advantage of. If only a very small numbers of users are doing this then I don't see it worth the dev time to block the email providers they use possibly hurting valid customers. Just leave it alone. I use Relay for services I genuinely pay for but don't want to give out my email address in case of leaks.
