Yeah kota, if people loose track that's life. But u can always go back a few steps, search for a thread and get way more info from one thread then tracking down a head in multiple threads, looking at dates and such.

Example:
Artist:Pheature
Previous owner:HiPower, Tomiiiwhaw, insanity, imapirate
Size: 512x512
TC
next person that buys it should add name to this list. Idk it might work in case of lost files to.
