So, I think there is some additional gatekeeping: ability to ignore the fact that the one day the community decided to personally make me a target of their vitriol. :(
This woman captured the image of me with my dog and posted it for her feed calling me a slue of slurs and various labels. I spent the next few days in bed and was afraid to leave my house. I had to delete my Twitter, scrub the internet of that image, and get a new email address because her followers would not stop trying to contact me to continue what I could already see them saying on that Twitter thread. It took Twitter over a week to remove the thread, even though it clearly doxxed me and violated their policies barring inciting harassment.
Personally, I think some people just wake up and choose violence, and other minds can't help but dabble. Sorry this happened to you.
Why would the "hentai/alternate" board be targeting you? Even "insulting" you, rather than the norm of posting hentai?
