Script to item links was... reverse engineered I guess? So you can do any colour, name and stats. DC means just that there is no item like that in database and client derps 6_9. I wouldn't worry about it, it's same with WoW before when you tried to link item that didn't drop at all on server yet.
Yeah people push those item links out. I saw one the other day for a 2handed sword. Clicked it and didn't disconnect but the sword that came up was something way too powerful to be in the game. Something like 15000 dps.
