> Some sites, instead of using a blacklist of every single disposable e-mail service, just use a whitelist of 'popular' email domains This is very interesting to me as I've had my own domain for a very long time and haven't encountered this more than twice in that time. If you don't mind sharing, on what kinds of sites have you seen this? I am not at all discounting your experience. We probably have different interests and visit different sites so I'm interested to explore that. I have very often hit the "you can't use emails from that service here" deny list which is why I think these kinds of services are neat but will quickly be rendered useless once the deny lists are updated.
