ENS is an abbreviation of Ethereum Name Service According to the current policies: "The Public Name Tag must clearly identify the smart contract in a way that cannot be mistaken for any other contract. To prevent ambiguity, it must always include the project name and contract description, separated by a colon and a whitespace (e.g. “[project name]: [contract description]”). This holds even if the contract address is known by a shorter or abbreviated name in a different platform."

ENS is one of the most famous projects in the Ethereum ecosystem, and everybody calls it ENS. In addition, if I put "Ethereum Name Service: ETH Registrar Controller" it wouldn't have been valid either because it has 47 characters, that's bigger than 35 (the current character limit). According to the current policies: "The Public Name Tag must clearly identify the smart contract in a way that cannot be mistaken for any other contract. To prevent ambiguity, it must always include the project name and contract description, separated by a colon and a whitespace (e.g. “[project name]: [contract description]”). This holds even if the contract address is known by a shorter or abbreviated name in a different platform." The final sentence "This holds even if the contract address is known by a shorter or abbreviated name in a different platform." confirms that I did it correctly, because I DIDN'T abbreviate the *contract address*: 0x283Af0B28c62C092C9727F1Ee09c02CA627EB7F5

ENS is a well-known project in the Ethereum ecosystem, it is hardly to be mistaken in this context. The project itself uses ENS multiple times on its main website and documentation (screencap evidence in the attachment, "ENS" being used about 10 times at the doc landing page vs "Ethereum Name Service" being mentioned only once) as ENS is interchangeable with "Ethereum Name Service", plus, even the website link here is "https://ens.domains/" and not "https://ethereumnameservice.domains/". In addition, ENS is actually a shorter/abbreviated name for the "project name", and not a shorter/abbreviated name the "contract address" itself as the challenger intended. The tag should be accepted.
