When I leave feedback, my user name appears to be different to my ACTUAL user name. Why?

[remote_dude]

I don't know who e***e is but the user name that should be appearing near my feedback is "remote_dude" of "r***e". My password was skimmed a few weeks ago and I am worried that someone might be mucking around with my Ebay account, even though there don't appear to be any other changes.

All feedback is coded....were you looking at it whilst not signed in?
