At 60 you are supposed to have a network of acquaintances and former colleagues to rely on. You broadcast that you are looking for a job and they reply with leads. But since you have to deal with recruiters like a junior developer you clearly don't have such a network. That indicates low likability to recruiters and is to them a red flag. They prefer someone in the happy median; stronger than average but not extreme in any regard. You are far from the median.
