You know that you are making your IP address known ALL THE TIME when you're using the internet? Unless you're browsing sites (or doing anything else) through an anonymous proxy or are using a sophisticated firewall Pyschostats should be the least of your concerns...
The "added value" from an admin's perspective is that he can ban you by IP address, can check from what country you are etc.
1) Regarding the 'added value', I still don't see it since that does not require the public publishing of your IP.
2) I figured I would get a response like: "you know that you leave your IP address every time you visit a site etc. etc.". For the record, I know. But
none of those sites are publishing my IP address such that 3rd parties can access them with extreme ease.
3) Unfortunately my question is still unanswered....
