For glitchless, if the rocks are already exploded or they fell in a way that you can go through would it be disqualified?

no, that's why we reset until we have rocks that are passable

I have another question, considering we can "continue when rocks are passable", isn't that technically still considered help from other players? And even if it isn't, could I not just remove the rocks myself and then start a new fresh run?

gekki stop exposing these very exploitable strats, i need my wr!!!

Sorry

The actual answer is that the current mods are so incompetent they won't even consider changing the rules.

It was discussed in the mod chat channel, and we've decided not to change the rule for the taiga rocks, so if you have it closed, you can retry until the rocks are open.
