I was able to pick up a Theck's Emberseal on Horde for 18k. I decided that I would flip it to Alliance and try to sell it and, worst case scenario, my DK or warrior could use it. (Not that great of a piece so Faid will replace it soon if I give it to her.)
I started getting undercut a lot so have decided to sell it exclusively through Trade, where I am asking for 25k. Here's some /2 from Argent Dawn when I was attempting to sell the ring:
yeah, he mad.
Anyways, things went on, still no ring sales. I decided to restock glyphs since I'm running low on a few and hopped on my shaman (in ghost wolf form, so this following conversation makes sense!) I went AFK to grab a popsicle and come back to an open trade window with 5 Hypnotic Dust, 5 Greater Celestial Essence, and 2 Maelstrom Crystals in the window. After a few seconds the person accepts the Trade, giving me the materials.
So now he's on ignore and I've got some free Enchanting mats! I'm usually the type to say "lol" and help someone correct a mistake. I haven't made very many, but having made a few small slip-ups when posting auctions (20 Volatile Air for the price of 1, for example) I know how much you kick yourself for that. But the opportunity to hopefully teach this guy a lesson about being a dick to complete strangers was too good to pass up.
I have friends in his guild, I'll probably send it to them and have them put it in the guild bank because God knows I don't need to rip people off to get enchanting materials, but yeah, too great of an opportunity.
Please, folks, from a trying-to-reform Trade Troll, remember this: Nothing good will come out of being a dick to someone. There is no positive thing created when you harass random strangers. The internet breeds a sense of anonymity that tends to make it so there's also no downside; nothing bad comes out of being rude to complete strangers who weren't even addressing you. But sometimes, at the end of the day, your dickishness will come back to bite you. Be nice, folks, and make sure you're trading with the right person before you press accept!
