[July 30 / Server Check] MapleStory

An attentive person would be able to identify items which are DEFINITELY out, and make up a list of items which could possibly be unreleased. From there, they'd just need to write down their list and punch it into cash shop and cross reference to see which items they thought might not be out that actually were.

It would take a lot of time and effort, but it certainly wouldn't be impossible to complete over the weekend, not if the person puts in many hours.

Items change, too; sometimes items are removed from the cash shop at random intervals without any sort of warning. They'll then turn around and re-release them later on, after people have forgotten they were already out (I'm convinced this is what happened to some of the items in our previous server check.)

Yeah, someone could do it, but this isn't something I find worth all that effort.
