You're forgetting quite often anyone in the hack/spy process probably has about 10 tabs open to hack/spy potential targets.
Its not a massive problem, just irritating as it can happen quite frequently if you're spying a lot of people at once.
Like I say, I think I credit people with too much mousing ability... I've never clicked a wrong link in the game menu, let alone press an entirely wrong button, and the difference in shape, style, format and position of the "Hax0r" (a button) and the "Ignore" (a link) just seemed too great! I've never clicked "I'm feeling Lucky!" instead of "Google Search" on Google's home page, for example, and they're the same distance and both the same style and shape, too!
Maybe loads of you do that though!
I've never played Bush on a mobile though (I don't and have never had/used a mobile with web ability), so perhaps that's where the problem stems (I don't know how difficult it is to click on a link in mobile browsers, perhaps the margin for error in clicking the wrong place on a screen is particularly big).
