Looks like one of the pictures is at fault because it mentions sbnation as the source.
Yeah - I've been going through the thread and trying to figure it out. It appears they've gotten flagged and it's probably because someone may have hacked into their server and inserted something. There's a Plesk exploit that a lot of sites got hit with that allowed people to insert malicious code, and it caused them to get flagged as a distributor of malware. So I'm guessing that's what happened.
Needless to say it's definitely on their end, not here. I'll just have to go through and find the images.
