In reply to Rob Exile Ward:
I don't think I've ever been to Cubic Block and not found several climbers there. The Rough Wall face is always green, even when dry. This year it's rarely been dry, which may account for the apparent neglect. But it doesn't help that the National Trust are doing their best to put people off - loads of new signs threatening anyone parking outside their pay-and-display, parking fees £5 even for an evening visit, and the gates locked "at dusk" - which on at least one occasion this year meant just before sunset.
Caley in the summer tends to be a bit of a midgy hell hole, and in the winter, the routes tend to be a bit green. But the thing that tends to put me off visiting more is that it tends to be used by local youths for getting pissed, and there are usually loads of discarded cans, barbecues, etc.
Try Almscliff, Ilkley Quarry, or Heptonstall, and you'll see where all the climbers are.
