Muletodooffers
Did it also ask for your gender?
Nope. It did not, but I was just scrolling through them to see if there was one I liked and after not seeing that one again, I just decided I'd let them play in the background until I found that one again, since there would be fewer videos for me to watch with each one and all but one video disappeared after putting in my age.
The only "video" offer that remained was the one that requires you to sign up for a trial.
So apparantly all of the offers I had available from them are not for 21 year olds.
