Hey, I'm so sorry to hear you're being bombarded by people like that. I was only worried about the lifting of words directly from Riordan and what others might think of the Kofi (unlinked) in your description. I'm not sure who decided to go above and beyond to harass you, but I hope you're able to report them on Discord, here, and Tumblr. If you ever need anything, please feel free to reach out. You can find me @trailshome 0r @clamoribusrogamina -- I'm happy to listen to you vent or just shoot the shit or smth.
I've watched other authors get harassed and have been harassed myself. I don't know how much help I can be, but I'm always down to lend an ear to a fellow author. Wishing you the best and am excited for updates to your games. (I adore Moreau sm!!)
Sending you hugs and well wishes!! Don't let those posers get you down! They just want to start something to start something! <3
