Some of the advice isn't awful. Someone being over their ex is important, and Especially the ones based on age don't take a huge number of things into account. Someone saying they aren't ready is a nice way of saying not you, but the author really has NO idea why the guy might not be of interest or what she's looking for. And most women are professionals these days, they're not waiting for anyone else's money. Different opportunities pre-digital, issues with culture, sexism and success and female intellectuals, being athletic or into fashion or similar that may cause one to have younger friends. Some of these things just aren't red flags, it's weaknesses in culture and acceptance of women.

This author is mostly writing cute stories to keep you interested and I've begun to wonder if she's actually a woman. A woman doesn't call another woman damaged goods. Doesn't happen. She ISN'T goods at all. She would also understand the aging thing better and would be more sensitive to the cougar/cub thing (slurs) and talking about a "wall" wouldn't happen with so little sensitivity. So I think you're hearing anger from an dating failure posing as advice.
