After reading the CASPN page i have my thoughts upon the activity logged of various activities.
The littering of sites is always going to be an occurence, unlike ourselves some individuals have a different outlook on the sites we love and like to care for, camping out at these sites is like a friday night with white lightning cider and a few girls for 'entertainment', plus the buzz of camping somewhere 'spooky' perhaps?.

Sacred sites are used by persons of various 'spiritual' backgrounds for the use of empowerment of items such as talismans for personal use.Hence the burying of talismans in the ground in the aim of embodying the energy and spirit of the place within the talisman.Sancreed holy well is a good example, although the clouties on the branches of the tree are not buried, people tie the clouties to the branches with the aim of bringing healing to others and themselves, the burying of objects in the ground works on the same principle.

Damaged stones with chunks missing would appear to be caused by individuals wishing to take away the energy and spirit of the place.Crystals and gems sold in shops are obviously not enough for some people.

Crosses buried in the ground would appear to be a continuation of the long running 'cleansing' of sites deemed 'foul' through use of sites by individuals who use these sites for personal ritual and the association with occult practices.
