Something similar happened in my region recently, someone new to josm managed to turn a park around 100m across into a 2km diameter circle, and mangled the ways nearby. A quick email to the user revealed he was new to josm and wasnt even aware of what he had done. Fortunately the mess was easily fixed, but luckily I contacted the bloke, and he was apologetic and continues to ask questions to learn how to use osm/josm better.
Sometimes the diplomatic approach can be best.
