I use a <firstinitial><secondinitial><surname>@gmail.com and have been getting Facebook resets every week or two for years. But I know at least two people in two countries with a similar name keep giving out the wrong address from all the crap I get confirming their hair appointments and organising their BBQs, so it seems benign rather than a hacking attempt.
I take it as karma for all the junk <verycommonname@>hotmail.com must get whenever I use a public wifi network. Sorry verycommonname!
