idk compare ip addresses, take self-shots of both of you kissing, give out your addresses Anything that will identify the IRL you. BOTH of you.
Refusing won't help. Either you prove you're not CW94 or forever be condemned with assumptions that you are David.
Well I can tell you guys now that David and S4 are not the same person. Their IP's don't even originate from the same country. On the other hand I do believe that S4 is Sophie, she even admitted it on rst8's comment on her profile.
