You did the right thing.

I am not here to defend either of them, I am merely trying to gather and provide as much information as possible.

“The goat” is self proclaimed 10 years old, and nothing they have done makes me believe otherwise. I can assume their sister is of similar age, so this genuinely looks like a case of children not knowing boundaries, and they naturally tend to be more self-centered (if you have ever played a Roblox game and encountered a “dodges” type of roleplayer), so she took to creating a “canon” relationship with your character, without waiting for consent.

In cases like these, it is hard to really do much of anything, because let’s face it, children are stupid and stubborn (which can be super frustrating). You cannot rationalize with them or relay complex ideas. The BEST thing you could have done is block them. 👍

i seen the recent stuff, either way, I don't agree on their idea is all

them trying to push it to be canon is my only issue

I done blocked em and their supposed brother, as I don't deal with conflict wonderfully

From my understanding, clorince is likely immature (not as an insult, but as in I genuinely think they may be a child). They have that general artstyle and energy, not to mention that parasocial “post your every thought” mentality. It does not help that their grammar is pretty bad, which assists my theory.

All in all, it does not look like they were trying to ship you with an OC, but rather they were trying to create a sort of sidekick/pal type of relationship. English may not be their first language, or again they could just an actual child and bad at words.

As for the drawing without consent thing, I cannot condone that, especially since you explicitly state that it is outside of your comfort zone. Plus, due to the confusion with their word choice you are likely super uncomfortable and grossed out. I would try to get them to delete their posts, but they probably do not know how.

...I have a burning hate for them

that and im 80% sure their finna steal one of Cheesecake's ocs now

maaaaaaaybe a ban..

Well tell me if they ever do it again
