1- does showing non-nude but Sexy (bikini) video consider adult? 2- masturbation is considered adult?
I'll say more: the Adsense account of my friend was absolutely banned because he put image with girl in swimsuit..
Its more the theme some sites get banned even if they have no adult content or if they have keywords which google links to an adult theme. A strange example (in my opinion) I fell foul of was teen girls which to me is none adult but they would not allow it on adwords. From an adsense perspective you have to stay away from anything which could be miscontrued as adult oriented, not just actual adult content since many of Google's T&C's can be interpretted in different ways and of course their way is always right not the customer.
1 - probably - anything remotely related to sexy stuff is a no. for the 2nd, absolutely, I'm not sure how you could even question that.
It doesn't matter. Masturbation is sex therefore it's adult. Think of it this way, if you wouldn't see it in a disney film or on sesame street then it's probably adult.
how about accident clip? is it allowed in adsense? how about some sexy/hot girls dancing, is that adult? may be bikini?
Accident I don't know.. The other two are borderline IMO. If it's sexy google probably won't much like it.
Depends what the "accident" is. If you're talking "slips" I think you're on very shaky ground...which has a crack running through it...and is starting to slump off the cliff.
