A brother-in-law when he upgraded his PC, though I didn't think any of those emails I've since delete were anywhere close to any of his, nor did I think he would have tried logging in seeing as he isn't afflicted with the same points/miles disease as I.
As mentioned I cleared all but my regular email address and that seems to have solved the problem for now. Thanks for the ideas, all.
