If your browser starts screaming at you when you navigate to the boards, Google’s been fucking up the last week and triggering false positives. Safari, Chrome, and Firefox all use Google’s shared system. In reality there is nothing wrong whatsoever (confirmed by Google engineers and their own tools via lengthy and angry correspondence). The messages have been coming and going for a few days now.
You can either click through the warnings incessantly or disable the useless “Safe Browsing” check. Your choice.
UPDATE: We are no longer utilizing Google Analytics or GoogleAPI services because of the recent shenanigans. We are now using in-house solutions.
