You really can't be certain that there's anything going on here other than people being weird or flakey, and even if you were, there's nothing all that useful to be done differently.
People will spend social time with people whose company they enjoy, even if they hear nasty gossip about them. The only real defense against gossip is being the kind of person who other people find it difficult to believe malicious rumours about.
It can take a while, but someone with a habit of slandering members of a community will eventually find themselves being the one who winds up with a bad reputation.
