Honestly it can't even detect autoclicking to train skills on RS. So many players with over 2b xp that I've seen do it and are quite outspoken about it.
We apply an average of 71 offences per day to players who auto-click in RuneScape (not counting OS). Whilst it's something we'd like to more proactively tackle, there's more damaging bots which we need to maintain focus on, but rest assured we do take action. Please report any players you suspect of auto-clicking too, as they will be reviewed on a daily basis.
