Using a META REFRESH to handle the URL for the destination, the hack successfully prevents the referer header being set. As using META REFRESH is one of the ways in which to prevent referer info being set. (Another is using SSL for example.)

This means that the end site cannot see where the request originated... it basically is anonymising the requests of your user.

You might think this is pointless, but some organisations such as the BNP in the UK frequently check their logfiles and visit sites that links came from. In this instance using this hack will prevent a political conversation from being invaded by trolls from sites linked to.

In a one-liner: It anonymises hyperlinks on your forum by preventing referer information being sent to the end site.
