Again you are all missing the point here. Most hackers get access to your
UO accounts by hacking your EMAIL addresses - the threat of spam is utterly irrelevant. If anyone on that email list is a wannabe hacker (since this isn't REAL hacking anyway) they will get into your very unsecure Hotmail address and request your account name and password from EA.
I recommend that you all register email addresses through more secure providers (your ISP for example) and set up your Ultima Online accounts email address through them. OR set up new accounts specifically for
UO and don't use that address anywhere!
