It's unbelievable how some people behave! Sorry you've had this trouble and I hope he gets what he deserves!
There is normally one on every site (or in every group) who thinks the rules do not apply to them - it sounds like you are doing the right thing in your response, which can be difficult when emotions run high! just be careful not to loose you rag when you see the offender!!
I think it's the same person. Wish I could get a small CCTV camera that runs off batteries and an SD card. I'm sure my allotment neighbour would let me put it on his shed, just under the roof which would more or less conceal it.
Maybe someone feels guilty.
