hello d-man97, mozilla won't share your mail address with third-parties, advertisers, etc... have you checked that you haven't made your mail address publicly available as a part of your addon's listing or that you've come across something like this: http://news.cnet.com/8301-1023_3-57594819-93/google-starts-placing-ads-directly-in-gmail-inboxes/ ?

From: WordPress.com <user-experience@wordpress.com> "Howdy!

If it wasn't you, maybe it was GitHub?

If it wasn't you, maybe it was GitHub?

just to avoid any misconception, i'm a normal user like you (and also happen to host an addon on AMO), so i obviously cannot speak for mozilla authoritatively.
but judging from my personal experiences (as far as i 'm aware no piece of information that i've provided to mozilla has gone to any place it shouldn't be in) and also from my insight into the kind of conduct of the organisation i feel quite confident to say that your address didn't leak from mozilla - they also would have quite a reputation to lose.

maybe it's best to drop wordpress a line and to inquire how your email got into their system...

Yes, I am aware you are a normal user! Thanks for your help.

I already have requests out to GitHub and WordPress.

The thread continues, the answer is there: Mozilla created a WordPress.com account without my permisson.

Spoiler alert:

Wordpress.com accounts are created when you use Gravatar to create an "avatar".

And why would we need to do that? I dont want any more cross-site scripting, nor wordpress account (they recently got hacked, and many users e-mail accounts were taken over and were sending viruses.) STOP the madness.
