I was hanging out in GToB until me and two other people noticed the Necro's with bot like names. behavior and all wearing Istani armor first running to the trophy honoring Everfrost and then to the storage. At first we we're taken aback by two points.
1) This is the freaking Battle Isles. What are the possibly doing farming faction?
2) They we're all level 3 which meant they had to be PvE characters.
3)WTH can you farm in NF at level 3?
So me being bored and having nothing to do I went to Noob Island and looked for them.

These we're about 90% bots. <.> (I had to edit out some real names.) So they then proceeded to run to the Sunspear Recruits to gain more exp before running back to First Spear and warping away.
My guess is this: They take the quest chain of Rally the Recruits (Tutorial) > Into Chahbek Village to get to Chahbek Village. Then the repeatidly go to the Training Area in Churrhir Fields and farm the Iboga Roots for their Sentient Roots.
Since Chebek Village has no Storage their programmer makes them warp to GToB to dump everything in the storage. I think... I have no idea how botting works but shouldn't it be like..something thats earns way more than 3g? Though with the amount of Bots that we saw..we thing the quanity makes up for the lack of price.
How do you think Anet's going to handle this one?
Edit: I can't get my pics uploaded on the site. Here's a link ---> Mod Edit: Bots are people too. Feel free to repost the screenshot without names
