It's very sad when one sees that the Mountaineering Council of Scotland guidelines that jonnie3430 has linked to above (specifically, item 7) are being so blatantly flouted, as evidenced by this logbook comment on the mega-classic Centurion, dating from September last year:
'Brilliant line up this monster of a crag. shame about pitch 5 its a bit scrappy also not impressed by the amount of damage that has been done to pitch 1-3 by winter climbers.'
