Use other email services then hotmail like yahoo and gmail. Haven't tried this but I presume it works
Have you tried hush.com?

Create the account, then load rs, create the account on RS, then go into your created email address to confirm it. You can make unlimited email addresses per hour (and then have no password), so it's much quicker.
Wait do you have to confirm the email now? I used to make random names like [email protected]
you can always buy your own hosting and then go from there, takes like 5 seconds per account
This is really the best way, as unlike all these temp mail services if you run your own mail server you can always have access to the emails, which is always good for recovering accounts encase anything were to happen to them.
There might be free mail servers around, or at least some that are cheaper than buying a whole hosting package. Browse around!
