I got this message from "eBayAU" today, I didn't click in the links.
The bit.ly links are suspicious, however one of my ebay accounts I just have "K" for the first name and they also have my mobile number.

99.9% sure it's fake but any chance that it's not?
Looks legit, as part of the $20 off deal.
