Same here. All links to forums showing as "unsafe:/thread/...".
Reviews, too. But not Geeklists.
Noticed this. Seemed to kick in right after the bug fix for what had caused several topics, such as 'Buying and Selling', to vanish. Those topics came back after the fix, and the 'unsafe' bug popped in.
I spent a fair bit of time trying to see if there was a plugin that needed updating, before finding out the links themselves were being inserted as 'unsafe' in the rendered HTML.
Issue, for me, occurs on IE 9. Firefox 22 worked fine, for both issues.
