I have an ex who will simply not leave me alone. He has sent text messages, emails, whats app messages, facebook messages despite my repeatedly asking to be left alone. I have blocked him from all forms of communication but hes now messaging on here and i cant seem to block it. is there a way? its ridiculous and im actually thinking of giving up geocaching and deleting the app from my phone because of this problem. Obviously im loath to do this as i actually enjoy geocaching, so if anyone could advice me how to block him, it would be greatly appreciated. Many thanks.
