There is no such thing as "leaving the furry fandom". All furries who claim to leave the fandom just do it for the attention. It's the equivalent of "guise, I'm leaving the United States when (insert name here) becomes (insert thing here)". They never go through with it.
Either the furry comes back and says "hey guise I couldn't leave I missed you guys soooo much uwu!" Or they come back under a new name/fursona and just glide on from there.
In this case, they're just exceptional and try to glide on back in, ignoring the fact that they had an Uber dramatic episode just a day before.
Artists or youtubers only come back to the furry fandom to get those sweet sweet furry sheckles because it's the only thing paying their bills.
Kothy really really needs those sweet sweet furry sheckles to crave his porn/food addictions, without it he's just another normal dude that will never feel the softness of a vagina again (if he even ever has)
