The 2nd one isn't against TOS. This is a person that got stuck with all his friend's guinea pigs. Instead of flagging him, I would email him a list of rescues in his area to make sure all the pigs go to great places.
He's still not a horrible craigslist ad.
He might of stopped all communication because he's not getting any money for the pigs. I am surprised that 1 rescue was willing to take all those pigs. Hopefully these pigs find their way to good homes.
