Just in case you missed this, I copied it from UO.com :

Scam Alert
We have received many complaints of accounts being hacked after the account owner created a login at a particular website, which purports to offer UO gold in exchange for filling out surveys. While we cannot say for certain the problems are connected to this website, we can say with certainty that there is no such thing as a free lunch.
We strongly suggest that you do not reuse your UO account name and/or password anywhere - particularly not at a UO-related site. If you have recently typed in that information during a visit to a website offering free Ultima Online gold or items, we beg you to change your password immediately.
If you need to change your game password, log in to "Account Management" from the main UO site. Be very, very wary if someone offers you something for nothing.
