I am not sure I would worry much about harassment via Morse code. It wouldn't be a source of new bullying in the way a social media site would be, so I can't imagine how it could make anything worse
Providing an avenue that students could (and almost certainly would) use to direct slurs at one another, seems like a surefire way to make things worse. I do share your concerns about social media.
In Los Angeles I’ve watched business after business close because their rent was increased by their commercial landlord only for the property to sit vacant in some cases (no exaggeration) for over 5 years!
Thats absurd. Also as a business owner who would like some space to work out of your only options are endless swaths of vacant industrial buildings that are tens of thousands in rent a month. I don’t quite get how anyone runs a brick and mortar or has space to do anything profitable.
