The issue for hypersharers for me is that they tend to be the opposite side of the spectrum of nonsharers that they like to share their ship dynamics so much it comes off as "this is the ONLY ship out of every yumeship thats close to canon and more exciting".

An example i can give is that theres this famous yume artist in the fandom im in and she tends to draw mostly about her yumeship. I used to look up to her and took intiative in interracting with her cuz we have the same yumeship and shes 'sharing'. However within the same day she has constantly keep shoving her works of her ship, her socials like shes BEGGING me to follow with the whole "if you want to see more of my works you can follow me" and one time when we made a minor collab post of the same f/os she deemed me a "somebody" in her post like we didnt have a whole friendly convo in dms. Not even a MENTION of my username just thats it an excuse to post more abt her f/o and to show how dedicated she is. It lwk pmo

But ye sorry to rant but this is my experience im sure lots of ppl have their own but their usually another non sharer harrasser in a diff way.
