I completely agree websites and apps should take a hard stance against harassment and should carefully consider how their platform could be used to harm others. It seems that Twitter is perfectly suited for mass harassment without giving users any recourse other than quitting the site completely.
It’s really saddening social networks don’t make it a priority to prevent this type of behavior. Next-generation social networks should take heed to your story and the thousands of others like it so everyone can have a better experience online.
Again, I’m sorry that you had to deal with this BS and I hope you find another platform.
