Often in forums, comment boxes, blogs, etc, you may see that you and others have visited before at a certain date/time. Sometimes you see OTHER users' details: IP Address, country, etc. which may not have been expressly consented to by the user. Certainly it's legal for a site to record your visit in the form of your IP address, date/time, etc. There really shouldn't be a question about that. Who knows the kind of logs that ISPs keep.
Question: Do you consider it to be in bad form; sites that publicly post/expose/make available your IP address (or even country flag) in connection to your login/username?
