We all know people like to mislead people in URLs: www.google.com
I personally think any URL in URL BBCode should go through a redirect process ON the forums. A page that just says "you are visiting {URL}. If you want to proceed click here* if not* click here to return to where you were previously". Again* it can be enabled/disabled via admin CP but I think it'd be useful.
I also think it'd be useful to integrate tinyurl support. If you get a tinyurl - it automatically runs it through preview.tinyurl.com to see what the actual URL is.
