Hack idea: Bazaar population counter?

Hey guys, first time posting a thread so go easy on me. Anyway, I was wondering if there was a way someone could make a hack that showed how many people were in bazaars. It would make it infinately easier for me to find people hosting shatters, which is my main goal right now.
Anyway, just an idea. Thanks!

Could be done only by placing bots on every single bazaar

Maybe you could suggest Realmeye.com to do this. They got a bot on every server anyway
