Okay, so it's a very hypothetical question.
I'll tell you where I come from ...
Last year, on Stack Overflow there was some sort of fake account made and I have no idea why that guy/girl upvoted all my answers .My reputation increased by 200 (That's the maximum ~thank god !) and I was pretty delighted but the next day I got a huge moderator's notice and my account was suspended for like 3 months or so [I don't exactly remember the time :-( ] My reputation became 0 and I could answer no questions .
My question is:
If I upvote someone's answers genuinely out of interest, will his and my account get turned down the same way?
Finally, I want to know the logic behind identifying scams vs genuine questions.
And also the answer to my above question.
