I was part of a decently sized reverse engineering group there. A lot of valuable knowledge and interesting discussion is stored on G+ for some bizarre reason. It was never a great idea, but it's there and I suspect that there are plenty of similar groups that used G+ that simply aren't hellholes. Your anecdotal experience doesn't mean anything when there are clearly people who believe there's something there worth saving.
