Weird spike glitch!

Sorry guys, not a creetypasta, but I wanted to post this... this is actually true!

So I logged into aj, just like every day. I was looking for some den stuff (I forgot exactly what) so I went to one of the trading parties on the list. I found a jammer who had the item I needed, so I started to trade a few of my rares. Then, I noticed that there was something new in my inventory: a spiked collar. I clicked out of the screen and went to my inventory, but the spike was not there. So, I tried trading again. This time I saw that it had an ocean item symbol on it, which explained why I could not see it. It was a diamond shop spike that looked a little like the diamond encrusted gauntlets. I thought someone had hacked it into my account, so I quickly traded it away. I didn't want to get banned, not when I had just gotten bat wings!

I never saw it again. It might have just disappeared. Or maybe some jammer has it.
