Re the ethics of this. It makes my piss boil when shit like this happens, stuff gets trundled/chipped/graffiti'd/bust.
A bunch of cockends, presumably (and hopefully in some respects) totally ignorant to the significance/history behind something like this, and think its perfectly acceptable to drag/damage/scar shit out of the way, without seemingly consulting anyone about it. It always looks a mess, takes nigh on decades to weather, and even then, it never looks natural, you can always tell that mother nature didn't arrange the rock like that.
I'm never, ever going to be strong enough for the joker, but I dont care and that's not the point.
As a kid in the 80's, my first ever climbing trip was to the plantation and we bouldered on the pebble, even then, as a crappy Vdiff leader, I could see that bit of rock and think that's an obvious problem. I was a regular at the plantation for my early years and it was clear that one day, it would go. Eventually, Jerry solved it, and then extended it.
Putting the boulder back in place, sends out a firm message that rocking up and fucking about with stuff, without any consensus wont be tolerated. Just in the same way that chipped holds, where possible, should be sympathetically filled in.
I think pinning it is not actually a bad idea, just in case said bell end comes back again and moves it again, causing more damage scarring etc.
Funny how nobody is ever about though when it happens giving me the sense that who ever did this knew it was a bit 'naughty'
Re moving it back.. seating it back into the 'socket' from which it came might be a bit tricky, since that 'socket' might well have changed shape now, i.e. had loads of earth washed in/out from yesterdays biblical rain storm.
Oh and another thing, just looked and there is nothing on the other channel about this at all. I'd have thought it would warrant at least a news snippet, even if its just to get the message out to the masses that this kind of thing happens, and is generally frowned upon.
