Non-normalized names do not follow the existing ENS standard. These names will not be supported by most platforms and dapps.
Therefore Categories/Clubs (listed on ENS.Vision) that contain mostly names that are non-normalized are flagged with a yellow warning sign. Depending on the ENS standard, these names may or may not be normalized in the future.
The warning sign will be removed if the names get officially normalized by the ENS normalization. For more information please click here.
