I once got a warning for site rule 4 when I told a fetishist she shouldn't be in a subreddit for minors regarding that fetish. Somehow that was suggestion sexual exploitation of minors. I suspect that user reported my comment out of retaliation to try and kick me off reddit. I didn't appeal it because I figured i would just avoid that topic in the future and it was only a warning, not a perm ban or suspension.

I think you'd be hard-pressed to find a LinkedIn alternative. It's too business-oriented for anyone to care that it's under corporate control. In some sense, that's the whole point.
My understanding of Friendica is that it's supposed to fill a niche similar to Facebook. I've never used it though.
