Fizzie41 is part of the OSM DWG and is one of the maintainers of quality of the map.  However it appears one of the reverts done ended up colliding with another and ended up with the current mess which will need to be investigated.  Anyway the block on Casey Painter was a 0 day block and edit privileges have been restored after reading the block message: https://www.openstreetmap.org/user_blocks/15098 however there is still possibly an outstanding request on the source of the contributions, of which grace period seems to end today.  I'd (or Casey Painter) should still contact the DWG with the requested information
