I always do this way:
Scammer: hi
Me: howdy
Scammer: do you want a +7 on your weapon?
Me: (pretending to be noob) oh yeah, i want that

Scammer: i can help you,but you you must drop your weapon on the gound...
Me: why? (pretend like you really interested in this process of makin +7)
Scammer: its glitch, i maded alot of +7 that way
Me: Cool

Items share PT, you accept
Scammer: follow me
Me: Yay, ok

Scammer: ok,i'm gonna stand far away from you so you'll be sure i dont take ur weapon
Me:
(now play with him)Yo uare too close...still too close. Ok, i think that enough.
Scammer: Well, drop your weapon
Me: I'm not really trust you

Scammer: do you want +7 or not?
Me: (dont lose him). YES, but give me 20k, then i trust you
Scammer: lol, 10 ok?
Me: ok

Scammer gives you gold
Me: thx

Scammer: drop your weapon now
Me: what weapon? o.0 anyway, see ya later

Scammer: hahahha noob
I like this method, i know, the amount of gold you receive from scammer isnt big, BUT, you scam the scammer, thats a pain for him
