All are afk-able, and IMO, it's one of the least likely ways of getting banned. Although you're in a group, a lot of your movement is masked by other players.
Granted, there are a couple places where Dungeonbuddy could use improvements, but overall, it's not terrible.
In all the times I've watched dungeonbuddy clear a LFR, I've never seen anyone called out as being a bot. Although it's quite obvious to me that there's at least 3-4 bots in almost every LFR I do. It gets a lot worse overnight, too.
