I know it's not the best way to make a name for yourself but I've stolen alchemy's, orbs of alteration, and other nifty currencies from other unsuspecting noobs in The Eternal Laboratory.
All you need to do is search public for people running maps. Check to see if one of them is in the Lab. If they are, join quick and get in the instance. Right away you have to leave. This is the important part. For some reason people fail to notice the green indicators in the corner of the map by the portal. When you join and leave, sometimes it takes a while to get started for them and you aren't even there to them anymore.
Now this doesn't work 100% of the time, but I guarantee if you try for a couple hours you will get some idiot to open a map because they are too lazy to wait for another person.
Recap: Join public map party, go to the Lab in their instance, LEAVE IMMEDIATELY, hide in the South corner by the portal, wait and watch some TV, wait for idiots to drop orbs or portals.
There isn't much in this section I hope some people have fun with this like I have.
