A fix for internal links, now [url]example.com[/url] internal links are allowed (if the allow internal links option is checked)
Email links are now more thoroughly checked if an email host is mentioned in the post... so that @hotmail or [at]gmail will not be allowed (if the stop email links option is checked)
Human spammers found a way adding links to their profile posts, by posting the links in their status (rather than directly on their wall / other peoples walls). If the option to stop human spam on profile posts is now ticked, this now also included the status message - Fixed.
Log Events: If a user is prevented from creating a thread / post / altering their homepage / about me, log the event is logged. This log can be displayed via Admin Control Panel >> Tools >> StopHumanSpam Logs. The log contains the message displayed to the user (the reason there content was blocked), the username of the offender, the time stamp and the content they attempted to create.
If the user is not yet allowed normal links due to the link post rules, this option allows users to add external images to their post (these would usually get picked up as a link)
