Guild Wars 2

As far as I am aware, you can only get banned for selling exploited runs, such as using terrain glitch in AC P1 to skip most of the dungeon, or kicking people and inviting other people in who pay money, am I correct?
So if for any reason I decide to challenge myself solo-ing a dungeon path(without kicking anyone or using terrain bugs), it’s legal to sell it?
I also think it would be a real cool thing if dungeons had a “challenge” mode which was basically the same dungeon for one, but with much higher rewards.

More or less only people who have exploited have been banned for selling runs, yes.

Selling runs is completely legal. See: https://forum-en.gw2archive.eu/forum/game/dungeons/Dungeon-Forum-FAQ/first#post3472006 for the dungeon community’s FAQ on the topic.

Selling the dungeon basically ~is~ the challenge mode, particularly in Arah. You can get 20 gp or more extra for your solo by selling the other four slots.
