I got the Bugdroid hat last night on CodeGolf.SE. The thing is, I never used (or even downloaded) the Android app.
Did this happen to anyone else, or should I be worried that my account got hacked (in which case, why would anyone use the app then)? As far as I can tell, there wasn't any activity on my account at all in the relevant time frame.
If I'm the only one this happened to, could a dev look into which particular activity caused the hat to be given out?
