Can people find my email or EA account through my Sims 3 Community Username?

Nostralian  No one can find your email through any EA platform unless you share it.  There's no way to tie your Sims 3 Community username to your EA account name either, unless you've used the same name in both places, as many of us have.  EA customer support can see all of this on the back end, of course, but outside of that, it's all private.
