Gents, allow me to shamelessly plug easy-web-beacon. It's a script on MY SITE which crafts web-beacons for sending in PM's and emails. The tech types here will no doubt be familiar with web-beacons, for everyone else, its a remote image sent in a message which gives you a remote persons IP amongst other things. This tool could help out trolls, dodgy foreigners and provide locations for people. In This thread it was no coincidence I knew he was from lichfield Obviously it's a potential threat to privacy and anonymity, but you get beacons everyday without realising it, especially on the WWW. Therefore I'd encourage anyone concerned by such things to block remote-images in their browser settings or use tor.
