Rob's second paragraph contains much wisdom and I'd agree.
Not sure I'd go as far as agreeing with his first paragraph though; I think more detail would be needed to make that judgement.
Speaking as someone who often finds it necessary to leave equipment in caves for long term exploration projects, it is very frustrating when it gets meddled with sometimes. A better option, if others dislike the rigging or whatever, might be at least to try and contact those concerned to discuss any perceived problem (e.g. via this forum?). Things are usually set up the way they are for good reason, which might not be immediately apparent to the casual self appointed experts? Then again, if there's limited rigging options, it might be a more general nuisance to others when pitched have to be left rigged. Surely the best way to tackle such circumstances is a reasonable discussion?
