I am very suspicious of someone who can't understand why offboard contact and giving out emails for pic trading is a bad idea without explaining it to them. There are only two explainations I can think of for this:

1.) The person is very stupid.

2.) The person is a cop/anti

And if it's the first one, I'm very suprised the person has not been outed/arrested by now.

I can already picture what yoda's response will be:

"what you mean? I'm no bad. I just want friends cuz I'm lonely. Gosh, why you guys no like me."
