The admin Anhn has very strict views on what is an acceptable user name. That your global contributions are completely uncontroversial is apparently not relevant. You can use Mall:Avblockering to request an unblock. 2A02:AA1:1608:5AA:AD70:A49D:1005:DFBA 28 december 2023 kl. 09.44 (CET)[svara]
I am sorry for the blocking. I considered the name to be a random nonsense name like "sdfjkl" where you just let your fingers run over the keyboard. Such names have sometimes been created with slight variations, which make them diffucult for a human to distinguish between accounts and can be used for obfuscating vandalism, and are mentioned in WP:Användarnamn as non acceptable. With your explanation, and as long as not a row of names like "nlsrdmt", "nldsrmr" ... are created, your name is perfectly acceptable. Sorry for the inconvenience, but I check newly created user names every day, and according to my opinion some vandalism has been prevented through early block of names considered to be random names as well as other types of unacceptable names, and this is with the risk of sometimes having a "false positive".

Just to visualize I list some blockings done by _me_ the _last_month_, for user names considered to be nonsense random names. The list does _not_ include blockings performed by other users, obscene names, list of names created in order to resemble existing users or existing living persons.
