A friend keeps posting on Facebook about missing children, and the kids have usually already been found. If she'd just click on the link before she shares it, she'd see there's no reason to post. She did it earlier this week and I politely pointed out that the kiddo had been found, and that the information was on the link she had posted. Someone with half a brain would've figured out that maybe she should read her own link, but no, she just did it again, and this time her link clearly said that the baby had been found in December. If she does it again, three strikes and she gets unfriended. Any other solutions?
