It takes a while to get used to the way things are run here. "Mall Ninja" knives, and fantasy pieces are generally looked down upon due to their bad reputation and the assosciation that they have with morons and their 1337 nifz.
You posted a cheap fantasy knife for trade on a forum that frowns very heavily upon such knives, thus giving you a bad assosciation. You seem to be a mature guy though, so if you stick around, find yourself some nice knives, and join the community as a productive member, this should blow over in with a bit of time.
Good luck with the forums!
