In reply to Rick Sewards:
Surely this is a handful of people:
Firstly, you have be climbing around 6c to 7c to be down that end of the crag.
Secondly they have the experience and knowledge to put up a new route.
How many people are in both those groups are lugging all the required equipment to bolt a new line to that sector?
Surely some people know who it was? Better for them to explain their reasoning and apologize directly to the GWT?
Otherwise I don't see how anyone who has ignored the rules that are already in place, will now pay attention to stricter rules. Because of that I don't see the rationale behind the ban. Once wildlife and flora return to that area, surely it would then be disturbing it to climb there again, so why would access be re-granted?
I would be worried GWT are just slowly removing the ability to climb there entirely.
Paul is right as well that 90% of climbers are more than happy to comply with the guidelines and restrictions.
