It's incredible to me that you don't feel any responsibility for a platform that you created. What happens on the platform is shaped directly by the choices you make as its creator - to be anonymous or identifiable, what the topics of discussion are, whether moderation happens.
By allowing anonymous commentary, scraping every student's data and seeding the conversation around "rumors", you created an environment that is perfect for targeted harassment. You created the platform and maintained it; what happens on that platform is absolutely your responsibility.
I highly recommend that you take this opportunity to do some introspection and consider why so many people were upset.
I honestly think the "targeted harrasment" thing is completely overblown. i mean that was just a very very very small part of the site. like okay, maybe 3 people are getting hurt (which btw, they could js report and id take the post down), but over four thousand kids were also enjoying using the site right? like people would come up to me everywhere and say how much fun they're having etc.
> consider why so many people were upset.
Were there lots of people upset? Or was it a small number of people with power who were upset? Like, I'm not at all surprised by how this played out, but it's not clear that anyone was upset beyond some people who don't take well to criticism.
