I like to shit on Taeshi as much as everyone else here, but she had a, somewhat, justifiable reason for the fan character hate.
She made the mistake of adding shitty vapid fancharacters, whose sole purpose was to be in love with one of the main characters and they ended up completely throwing off the dynamics of the actual setting and relationships.>Kizuna>LOL OMGGG DAVID IS SO KAWAII PLS NOTICE ME SEMPAI UGUUUU I'M SO CLUMSYYYY >Liam>I fell in love with Lucy incidentally after muh original girlfriend died>Carter>I love Lucy
And then you have shit like Kou, who was just a recolor of Mike, who had an edgy as fuck backstory and the creator claiming he was Lucy's 'original true childhood friend and love." Thankfully he wasn't in the actual comics, but his remnants remain in the Booru.
After making that mistake, Taeshi would get bombarded with shitty fancharacters that were basically recolors, and people constantly asking "CAN MY DONUT STEEL OC BE IN UR COMIC AND MARRY POLO??!!!? PLS RESPOND."
After that incident, she gave fuckall and decided to purge all the fancharacters.
