Right?! I don't get it how some people honestly say unless they can ban every average Joe macroing skills they shouldn't even try catching multiboxing idoc scripters.
I don't get how some people still ask questions like this when several posts have been made with the answers. Nobody wants to acknowledge the issue with resources. I'm still waiting for an answer to my previous questions to these same people with a realistic proposed solution.
I'll give all the assumptions it would take to do as you suggest and ask the question again.
So let's just assume that the staff of certainly less than 10 people (honestly MAYBE 3-4 GMs?) decided to start monitoring houses as a spot check. Then let's assume that nobody will complain about GMs picking the wrong "mega fall" houses (which they will) and let's assume they cover every shard in the game and not just the top 3 shards (which they wont) and lets also assume that nobody minds (or complains) that they are only enforcing the subset of rules as the GM see fit.
When the GMs are hidden there at a Tram "mega fall" with 30-50 toons ready to loot, how are they supposed to know (and prove) who is multiboxing when all the loot is sucked up? What's to say they don't make a mistake and ban you because they think you are a multibox account?
