I too had the ghost plane follow me. I was in the middle of nowhere, it was obvious it was me. It would be nice to have it turned off... i also notice the weather lagged a few minutes, flight following gave me better headings to avoid weather than I was ready to do based on the ADS-B data. I was going to turn right 10 degrees, they suggested 30 degrees and after a minute, it was obvious their data was more current. Info only, not airborne radar.
