First, you're ignoring the fact that the woman specifically runs a listserv for people looking for work. That's what the woman DOES. She helps people find jobs (supposedly). If what you do is help people find jobs, do not be surprised when people without jobs come looking to you for help with finding a job. It's like running a soup kitchen and going "What's with all these homeless people asking me for food?!" Second, what is it with people and the "almighty linkedin connections" thing? Do you or anyone else really think your "960+ connections" are some kind of treasure hoard that needs to be guarded by Smaug and kept safe from the undeserving? Protip: they're not. The issue here is that the woman's response was petty. She could have just denied the connection on linkedin and then made sure the requester provided all the required information to join the mailing list. Instead, she just blanket denies her from the mailing list with the intent of never letting her join because she had the audacity to ask for a linkedin connection. And, yes, people who are too full of themselves and hyped up on their own "importance" deserve to be knocked down a peg, which is what happened to this woman. Especially considering that this isn't the first time she's sent this kind of response back to someone. Without public exposure, she would have never been taught a lesson she desperately needed to learn - that you can't just shit on people because you think you're more important than them.
