1.) Wait for someone asking "Searching Enchanter for Moongose etc. I have the Mats"
2.) Whisper him with "I'm with Aldor Bank(Or OG Bank, whatever)" <---- Say exactly this and nothing like "I will enchant it".
3.) If he says "Do you will enchant it?" only awnser
"What do you think why I whisperd you ? ^^
" <--- Don't forget the Smiley
.
4.) If he trades the Mats to you logout.
So this was the Scam. I think it's unbannable because you never said you enchant it to him. The best Time to do this is when there's a free Character Transfer on your Server because this will damage your Reputation.
Sorry for bad English and sorry if it's a repost; I only try to contribute.
