yes and no. she could have quit all the time sure.
but she would have retained her stigma of being scamouranth. as you can see below your post, people already teaming up now and blame everything on the dude, she never wanted to scam. it was all him!
again, i don't say it is a fake! but i also don't say that she never would do something like that just to make more money and good PR. both is very possible.
