Way back when I was still on LinkedIn they suggested I connect with a neighbor in my apartment building. The only thing we had in common was the street address. We'd never spoken. I recognized her from being around, and that she worked in the store around the corner.
What finally pushed me out was they kept suggesting I connect with people from a former employer, which employer I would prefer to just forget. I'd even taken the employer's name off my resume.
I wonder what people trying to avoid abusive spouses and other dangerous people can do. Probably have to leave LinkedIn.
