Chaturbate and mobile traffic scam?!

I'm running Chaturbate affiliate and sending mobile traffic their way.
I have attempted to test user experience by registering myself. When I click signup after filling the form this is what I get.

I have not changed any safari parameters on my mobile? Wondering if it happens to all mobile users?
Seems really unfair, as user may comeback to chaturbate on desktop and register without affiliate cookie.

That do you guys think?
