I can't remember her screenname, but she posted yesterday about naming her baby Zayus and asked for opinions. She got some snarky comments, and she then posted today that she was appalled at the comments she got. When she was told that she was posting on an open internet forum and could take it or leave it, she apparently decided to DD.
It's not the first. Someone did it the other day when they were asking for opinions on a middle name for Avalynn, and most people suggested just using Ava. They also DD'd their f/u post in which they complained about getting unsolicited feedback on their first name.
