I remember back when I thought LinkedIn was a safe place, literally the only place that I wouldn't encounter someone in my DMs (or inbox, I guess). But lo, and behold, someone I accepted who apparently graduated from my alma mater and we had plenty of mutuals connections, comes up in my inbox with this extravagant monologue of sorts of how 'gorgeous' I am and all this extremely inappropriate stuff. I had to be like 20 at the time and, according to his info, he had to be late in his 60s. Needless to say I blocked/reported and realized that I really only can add people I already know here.
