See also: 鍵アカウント
I recently made my account private, so only my followers can see it.
Even if I send a follow request to that person's private account, it never gets approved.
Standard katakana spelling; widely used and understood.
Ateji spelling using 垢 for アカ; common in informal online writing but may be considered slangy.
Abbreviation of 鍵アカウント (kagi akaunto, 'locked account'). The first part 鍵 (kagi, 'key/lock') indicates restricted access, and アカ is a clipping of アカウント (akaunto, 'account'). The ateji spelling 鍵垢 uses 垢 (aka, 'dirt/grime') purely for its phonetic value.
