I've heard (anecdata alert!) that some men get frustrated and will start sending out "form messages" because they will take the time to craft meaningful messages only to get no reply

This was documented on the old OKCupid blog. I think the post was taken down after Match bought them.

Men grow frustrated and get tired of wasting their time, so they stop sending in-depth messages. Women are then even less likely to respond, which ultimately sends men into a downward spiral of desperation.
