I recently got a lifetime ban from a discussion forum!!**?? Although I can be a bit hasty with comments sometime I never offend so this rather confused me. On making contact it appeared that the culprit was not me but somebody using the same IP address. I know IPs are variable but I thought that they only changed following a full log off.
What worries me is that if an IP is used to trace a serious crime I could have spent the last week in Strangeways, or even longer. A bit worrying.
