" I was unofficially shunned by a gossipy sister who shared her lies with others. Pretty soon, other people weren't talking to me."
Change sister to elder, and you have my experience. I was unable to just explain to others, though. Since the information came from an elder, they wouldn't listen. Sadly, the information was MISinformation that the elder received from jealous in-laws. They were considered pillars of the community (and were childhood friends of the elder), so were trusted, even though they weren't Witnesses.
I was scapegoated simply because my in-laws wanted my house!
