I remember the time I spent on chat rooms in my past, I had several girls who would send me pictures of themselves in a PM, ask me if I liked them, and then continued on with asking me what exactly I liked about them. For some reason I always felt bad about ignoring them so Id say something generic like "you have nice hair" or whatever, but they were really really weird and made me feel uncomfortable : p
I wasnt even there to talk to them, but like even if I were it would be really obvious that they werent at all looking to get to know me but just to get me to give them compliments : p
