One thing I've noticed, you see the same shenanigans over and over. For instance, I just enacted a simul ship trade, for about 600 bucks worth of GW stuff on each side. The guy was very cool during the whole trade negotiation, answering all my questions, getting back to me in a timely manner, etc. Now, as soon as I mentioned I shipped and provided a tracking number...total blackout. The guy has a high rating, so I'm not worried about him sending, but I see people doing this all the time. Not saying this guy is doing it, but I typically see this, the guy will not return any pm's, will wait to get my stuff inspect it, then miraculously recover from whatever 'kept' him from answering pms and shipping his stuff, lol.
This is not really serious, but I wish people would just say "I don't want to simul ship" Even though Magicickaly Memories points out in one of my trade refs that he would,
More serious, and thankfully much less common is the "bartertown curse" that falls on certain individuals. I'm sure you've all seen it, you negotiate a trade, send your stuff and bam, the person falls off the planet completely. After you hound them for days, weeks, months....they finally respond with "I apologize, but I've had a (family emergency, death, divorce, apocalypse event) and could not mail your stuff." These are the same jokers that will also drag things out as long as possible, hoping you eventually lose interest. A buddy of mine is facing one of these guys right now, he's even called him on the phone, but as soon as he said "I'm the guy you were trading with," yep, you guessed it, the phone cut out, disconnected, hung up.
Any other shenanigans I'm missing?
BTW, this post is meant mostly for humor, and I am in no way accusing anyone of anything(except the guy in my first definition, lol).
