I have followed this discussion with a slight sense of disbelief. This was very topical 10 or more years ago but the world has simply moved on - or I thought it had! This genie was out of the bottle long ago. People who want to find archaeological sites and monuments have no difficulty doing so. Many of them have been marked on OS maps for many years. Or they can get the information easily from the NMRs or SMRs. With the modern requirements for freedom of information, I don't think that we could justify withholding information. The NMRS is about to back its online records, which offer full information, with online mapping. I hope we will follow suit in due course. In Humberside, in the early 1980s, I remember there was the full listing of sites published by Loughlin and Miller. I also remember metal detectorists telling me that they believed the grid references had been deliberately messed up to confuse them! This was not actually the case. No, the only answer is public education and raised awareness of they should not damage sites, and why sites are of value to everyone, not just archaeologists.
