Deleted Item and Forum Thread but item is still showing on poe.trade

So I made a trading thread a long time ago:

https://www.pathofexile.com/forum/view-thread/1179119

People have been messaging me to buy my Eye of Chayula from Standard for 2c and it got so annoying I went to standard and destroyed the item and I even removed it from the trade forum post.

PEOPLE ARE STILL MESSAGING ME FOR THE ITEM!! It still shows on poe.trade. What gives?
