Bycatch - Saving Recruiters from Accidentally Headhunting from Clients

Is anyone else surprised LinkedIn haven't solved this already? It feels like a quick-fix and semi-obvious feature for them to include, especially in the Recruiter Pro product? We tried adding notes to the individual LinkedIn profiles, but they quickly become outdated when the person changes employer. Equally, when new people join an off-limits company, we don't always know about it right away, so the notes never got added on. We settled for using a central spreadsheet with client names on, but clicking back and forth each time was so fiddly, and we ended up making some mistakes. We build this Chrome Extension for our own recruitment agency, tested it for a year, and then recently made it available to the public. Free trial available, and it only takes 2 mins to set up!
