As threatened, here's part 1 of my artist cleanup suggestions.
I've decided to post this stuff in instalments, partly because there ended up being quite a lot of it, but also because you guys may not necessarily agree with my suggestions as to what names to use. Some feedback would be welcome once you've read it over.
This is a list of artists who are listed under something other than what seems to be their actual pen names. I've struck through a few names that appear to be completely bogus (following my 100% thorough and reliable investigation...); the rest can probably be kept as an "also known as." Some already have the right name as an "also known as," which obviously becomes redundant once they're changed. There's also supplementary information such as Pixiv links.
I haven't attempted to romanise any Chinese names, by the way. Nor did I check every single artist, because that wasn't what I was originally trying to do...
0141zucker is Kuruto
12wesxd is Miharu
Twitter is ras0530, circle is Soumen Kingdom, so I have no idea where "12wesxd" comes from.
14yaki is Harasu
https://www.pixiv.net/en/users/34666626
1stfooom is Kura
1W2K is Aratagawa Nikei (currently the "also known as")
http://www.diced.jp/~silent/
310sa_n is Mito
https://www.pixiv.net/en/users/659974 (There's no yuri there, though.)
https://mitosan3.fanbox.cc (...but there is some here.)
32asako is just Asako
https://www.pixiv.net/en/users/191888
3692materia is Asama Kiyomasa
https://twitter.com/asamakiyomasa
5tb is Terano Terako
Also known as 5120Gigabyte (the circle name) and Yurigo Rira
https://twitter.com/5120Gigabyte
Obviously 5TB = 5120GB, but I don't see that name used anywhere.
8808808 should be 88O88O8
Also known as ᴋᴍ, which might be better as the pen name, but maybe it's better to stick with regular alphanumeric characters?
https://www.pixiv.net/en/users/1266345
8nznz is Haruhare
https://www.pixiv.net/en/users/17434275
_jo_er_ is just Joer (じょあ)
https://www.pixiv.net/en/users/11628043
https://twitter.com/_R18_jo_er_ Adult Twitter (approved followers only)
_lisamiqcpak is Kuroiro
__peach__o0 is Furako
僧侶@修行中 is Souryo
https://twitter.com/bozehead2011
https://acidcity.mystrikingly.com/
Also known as Yuri Satoshi here: http://barnstorm-design-labo.com/member/yuri.html
平安二郎 is Heian Jirou
https://twitter.com/pnzrrrr (main account)
https://twitter.com/heian3jiro (commercial work)
火の鳥~甲子園編~ is Radio Crusher Tokunaga
火の鳥~甲子園編~ is "Hinotori ~Koushien-hen~" ("Phoenix ~Koushien Volume~"). This name is not currently used, but I'll assume someone didn't just make it up...
炉LEE is LOLEE (Romanised as per Twitter account name, also it makes the pun more obvious)
http://monsterheart.blog100.fc2.com/
https://twitter.com/LOLEExxx
矢野まもる is Yano Mamoru
https://twitter.com/yaganome
精密度100%
Since this artist is also known as saramanda_kun, that might be a better name?
Or if anyone feels brave enough to decide on a romanisation, here's the Wiktionary entry.
https://www.pixiv.net/en/users/15633186
綿屡 is Wataru
https://twitter.com/yuridaisukidaaa
aa2233a is Akineko
https://aa2233a.wixsite.com/akineko
aabtcndneefkg is Kame
https://twitter.com/kamekamex1
admisrsr is (currently known as) Izumi Sera
ahhnh is Noha
akbskenmb48_40 is Mashiro
https://twitter.com/mashiro_elegy
alknasn is Suda Hitoshi
https://www.pixiv.net/en/users/3734404
almi is Koketsu
"almi" is definitely bogus: someone mistook the title of their doujin for the artist's name.
Aly is Kisaragi
https://www.pixiv.net/en/users/600944
"Aly" should be "aly_sos", but it's only used as their Pawoo address, so I'd say it's dubious to use it as a name.
Anarogumaaa is Mizuki Ichigo
https://twitter.com/kyunkyunhawawa
Again, "anarogumaa" is only their Pawoo address.
araki495 is Liku
https://twitter.com/liku_0495
AsH(灰) should be just AsH
(since the 灰 means "ash" anyway)
atn_jijifyg is Eiji
Atobesakunolove is Kaoruru
Aul is Hakuyou
aya223 is Pallas Cat
Banana_oekaki should be just Banana
("oekaki" is "drawing")
https://www.pixiv.net/en/users/52268240
bbr brbr is Bibiri
BDR08080 is Sanho
https://twitter.com/342g__love
They renamed their Twitter from BDR08080. Didn't know you could do that. But it shows that Twitter account names aren't a stable reference, for what it's worth.
Bloom2425 is Shion (or glasses_shion)
https://twitter.com/glasses_shion
break761 is lowfat
https://twitter.com/low_fat12
buson0120 should be just Buson
Chaka0w0 is Yama Chaka
chatora_yrkw is Yurikawa Chatora
chim is Tadak
chouge60229 is c8oyk
D11 is Yue
Da-cart is DAT
Daitaisonnnakanji is Yaa
dtvisu is Torinari
Enk_0822 is Eno-han
Eto is Suo
Evuoaniramu is MizuumiBB (or mzumBB)
Fakepucco is now usui
Description should be updated: "...and has no yuri on their Pixiv".
Faubynet is Kanata Noname, aka Fabiko
Fujimo Ruru is Fujimori Chocolat
Fujitaka Nasu is Fujinasu Taka
Perhaps they changed it around to avoid confusion with the other Fuji Taka Nasu.
Fuji_1221_ is just Fuji
Fulunukko is Nekono Hina (aka Nekono Pina)
Futanatu is Sinogiasa
Fuuga is Yuhane
Fw_moko is Izumi
https://www.pixiv.net/en/users/858264
f_tnbkr is Tenbukuro
https://www.pixiv.net/en/users/31034051
g-20800 is Oono
Gana is Kurosaki
Gensokigou is siho
Ginko is now sakaki (note all lower case, which is also useful to distinguish them from the other Sakaki)
Giselebon is just Gisele
("Giselebon" is only used as the URL of their website)
Gobou 1000 is just Gobou
Gorilla is GoriL.L.La
Green is Nadechika
https://www.pixiv.net/en/users/14478576
Gunner is Akari Kumato aka AkariKstar
gunzyou1 is Gram
That was a lot of effort considering that some of these guys only have one or two images posted, but I found some interesting things along the way, so it's all good.
As you can see, I've got as far as G, which is about one column's worth, so it seemed a good place to take a break. Lots of H coming up. Heh heh.
