I have a Stack Overflow account and I once asked a question about mounting sparse bundles. Now I just received an email from someone I don't know:

Hi you,

I just found your question about hiding mounted sparse bundles on stackoverlow. I just want to ask, if you got a working solution and if you could may send me the needed code. Im trying for days to get it working, but I don't find any solution… That would be really great! I also want to mount a sparse bundle without showing it in the Finder…

Problem is, I have never, ever posted my email adress on Stack Overflow, so how can this happen? This is not the first email like this I've received.

Well, you did, I found it in 10 seconds. Fix you github link. – Uphill Luge Apr 25 '11 at 9:19
Something to note: even if an address is hidden on your github profile the address is still visible in commits you make. – simonb Aug 23 '11 at 22:09

Your user profile links to your github page where you posted your email address.
I assumed something like this so I just went to your profile page and followed the links you posted there. Apart from moderators no one can see your email address you entered on Stack Overflow.

Great, thx. I think I'll add a comment to that in my biography box. Didn't know GitHub made my email adress publicly visible, oh well. – rightfold Apr 25 '11 at 9:23
@Radek Well, they do say Email (Publicly visible!) on 'Public Profile' page. But you can always hide it again. – Nikita Rybak Apr 25 '11 at 9:30
@rightfold note that the email address used on GitHub now can be kept private! See – VonC Aug 12 '13 at 11:43


  1. Open profile
  2. Follow link to
  3. See your E-Mail address

Bad form putting someone else's e-mail address out in public like that. – Al E. Apr 25 '11 at 12:44
@Al fair point, removed. – Pëkka Apr 25 '11 at 12:46
And finally we can validate if this is true... – Arjan Apr 25 '11 at 12:53
I don't know if anybody can delete a first revision, @Arjan. – mmyers Apr 25 '11 at 14:14
@mmyers, I assume the following usage scenario from Jeff most probably applies to first revisions: "User posts his or her password or SSN or {sekrit thing here} in a post. Don't laugh, it has happened. Revision has to be destroyed." So I guess the developers can just click that "delete" link for the original revision too. But: just guessing! – Arjan Apr 25 '11 at 15:12
Looks like to really remove the e-mail from public view, Pekka needs to delete this whole answer. – cregox Apr 25 '11 at 20:22
@Cawas yeah, I will do that (unless @Arjan there is an experiment running with this? Are you waiting for mod feedback?) – Pëkka Apr 25 '11 at 20:23
Damn Pekka, why took you 59 seconds to reply? were you sleeping or something? – cregox Apr 25 '11 at 20:28
