Welcome to SA amberky
I understand your reluctance to expose yourself to possible risk, but SA doesn't condone nor tell people how to get around the rules.
Some sweeps won't take "throwaway" addys - at least that's what I've heard, my guys use MSN & Hotmail & they've never had a problem that I know of.
TIP: Use an addy you plan to
always have - some sponsors only ask you to register 1x & pick a user name and password, which will work for all their FUTURE sweeps. If you change your addy mid-sweeps, it will look like you are trying to enter with multiple addys to them which can get you DQ'ed {disqualified}.
If you pay attention to the rules and read the privacy policies for the various sponsors, in no time you'll know at a glance what your level of comfort is with sharing your info.
Also, the COMMENTS under each sweeps has info we sweepers share with each other, so it's helpful too.
