I was submitting a tag alias request, from retasu_zasso to azuma_minatsu
reason:retasu_zasso is her R-18 twitter account name
On other sites (including R-18 ones), her names are always azuma_minatsu
https://twitter.com/azuma_m
https://twitter.com/retasu_zasso
https://azumaminatu.fanbox.cc/
https://www.pixiv.net/users/771029 (東みなつ=azuma minatsu)
but it shows this error, what should I do?
