I've just been contacted by a recruitment agent, and when I asked from where he got my email address, he told me from "Stackoverflow".
I was under the impression that my email address was not publicly available, as per the section under my settings entitled Private information (not shown publicly)
It's bad enough that these dregs of the professional world need to exist in the first place, so how exactly did he get my email address from StackoverflowStack Overflow / stackexchangeStack Exchange? (That is assuming he did get it from here, which is not proven.)
