It's not like Zer ever really stopped being a drugged-up rape-and-shotacon incest fetishist either from what I can tell, so you'd think there would be plenty of milk to go around, but she swapped identities and rebranded herself so often that it became somewhat impossible to actually keep track of her, because the minute she caught wind that someone had brought her up in passing she'd just jump to a new tumblr blog or stick her head in the ground only to pop up with another four alts like a goddamn hydra.
I think that swapping identities and rebranding is a big part of why people like Zeriara and Sevva-Phoenix and others of their ilk still come back so consistently; it's a combo of collective furry amnesia over past bad behavior combo'd with dumbfuck rhetoric like, "But that might not really be them, they have a different name and said they weren't, see? It's not like someone would lie on the internet about being a notorious individual to avoid reprocussions!"
Ultimately though that's why Glip and Eevee and most of Floraverse (barring Marl it seems) remain so prevalent and well-documented; they went so fucking far as to change their real names to variations of their fursona names. So it's much easier to keep track of them given they've only tried to hard rebrand like once and were immediately found out.
