The problem is actually finding that information, once a thread dies it becomes a nightmare to find them again and it's only aggravated by time as it gets buried under other similar threads on archiver sites. You can't really search posts by users due to the anonymous nature (you can, but using handles is frowned upon over there), most threads don't have title subjects and even those that do have hundreds of identical reposts every few days as they reach the max number of posts, or they simply die due to being buried by more popular threads. It's a fool's errand trying to recover anything from archiver sites that's older than a couple of days.
