In all fairness, there's quite a bit of difference between accessing one's bank account and accessing a forum where people go to whine about a 25 year old video game. I thought that perhaps this might be a good weekend for some folks to take a break from their whining, but nah... they just skip all the warnings and send their account passwords anyway.
And before I am corrected, and for people's information: It is not necessarily unsafe to interact with a website with an expired certificate. The traffic is still likely being encrypted, there is just no way to verify that communication is not being intercepted along the way. It's probably fine, I wouldn't do it, but if whining about old video games is that important... yeah, it's probably fine.
