In reply to seankenny:
Thanks for standing up and pointing out the error of their ways and their inconsiderate behaviour.
It is and has been a problem on Portland recently. This and other inconsiderate behaviour has upset and provoked the locals in the last few years.
There are respect the rock videos available by The BMC. Also there have been messages and threads on social media recently, but its hard to get the message out to the selfish and ignorant.
I can only say that vigilance and intervention of explaining the error of their ways by the more considerate climbers (or normal peaple as I like to call them) is the most effective way.
