When there's a naming conflict between two artist entries you should delete one and rename it to "artist_name_(deleted)". That way the old one can be renamed.
1st, stacc name -> actual name, with the former moved to qualifier. 2nd, same as 1st. 3rd, SNS handle (not just Twitter) -> actual name. 4th, Twitter handle -> actual name according to artist's own spelling (otherwise it's "shiromu"). 5th, stacc name -> current name. 6th, full name.
1st, old name -> current name. 2nd, stacc name -> actual name. 3rd, it's a provisional name, but I think it's way better than before. 4th, stacc name -> current name. 5th, stacc name -> Twitter handle. 6th, dunno where this was come from. Changed to his current name with the Twitter handle as qualifier. 7th, old name -> current name. 8th, stacc name -> current name. 9th, same artist. 10th, old stacc name -> current name. 11th, minor fix. 12th, old name -> current name.
1st, artist is Chinese, not Japanese. 2nd, adding spaces to follow the Twitter profile. 3rd, Twitter handle -> actual name. 4th, old name -> current name. 5th, old name -> current name. 6th, inactive Twitter handle -> actual name. He even introduces himself in English (My name is takeakigaku(たけあき学). ). 7th, I don't know where the former came from, but it's better to use what he uses widely. 8th, old name -> current name. 9th, stacc name -> actual name. 10th, old name -> current name.
1st, just "ryara" is enough. (130 posts) 2nd, old name -> current name where he uses it everywhere. (441 posts) 3rd, old name -> current name on Pixiv (looks like his BCY page is inactive). (119 posts)
