The "non-solicitation" agreements are so stupid. There is a cottage industry in headhunters where you tell your next employer who you want to recruit, then they ask a 3rd party recruiter to go track down that person after X months... and invite them to interview. I have seen it so many times in career.

It's definitely fuzzy. I mean, someone like an account rep or a financial advisor (and their clients) can't unknow somebody. So even if someone isn't taking their client list and calling/emailing everyone, there's inevitably going to be an element of client "poaching" so long as they're still in the same business.
