How far are you meant to take this, though? Like, the Genji dash boost of a wall is almost certainly unintentional, but it gives you an advantage to use it. What about animation cancelling Torb's hammer?

This wall exploit is obviously something that's egregious and certainly the player shouldn't be lauded for it (and definitely punished), but it's really hard to define rules against this sort of thing that don't punish honest players. Or, at least, it's hard to punish them without an "You'll know it when you see it" approach which isn't something that sits right with me.

I think the poster's point is that the rules aren't super well defined, and the same brush that paints this exploiter could also paint honest players using unintentional things (that could be considered glitches). The rules don't use any examples, and though this person should get their just desserts, it would sit a better with me if these rules were more well defined.
