ArenaNet posted the known major issues for the game, most notably the auction house and the partying system. They were testing the AH earlier this evening to a random 15% of the population to let it check capacity and now is down again. The partying system occasionally breaks which is why sometimes it's difficult to join another person in a specific area.
Where they mention botters will be banned, make sure you realize if you bot your account risks being permabanned. I'm not accusing anyone, I just have played other games (namely Aion and WoW) where I knew that people ran botting programs while they were at work to farm for them. They were banned in those games, and Anet is picking up the ban hammer now, starting with a light 72 hour ban, then after this week, permanently.
Crafting mats is not worth botting! :) We can all go gathering together, just ask folks, I know I hit up every node I pass by, especially mining, so the point I carry an extra 200 mining picks just for when I'm away from an outpost for a while. Lol
