If drawing the line on what is and isn't harassment is subjective, perhaps they should focus on building better mechanisms for individuals to take filtering / blocking into their own hands? One could argue that Twitter has these features already, but apparently the "privileged class" (celebrities) are incapable of leveraging them?
The article explicitly calls out their lack of product development as hindering the process. The example given is of a feature they've been discussing for 5 years(!) where it would favour displaying replies made by individuals the original tweeter follows.
I don't use Twitter, never have, but I don't understand why the platform doesn't have a whitelist mode, where only those people you've added to a list can message you. Seems like it would sort the problem for good, but I'm probably missing something.
I'm in the same boat as you on Twitter usage. But I suspect it's because being able to talk at anybody, including celebrities, is part of the appeal of the platform. The whitelisting mode you suggested makes it more like a one-way broadcast - you can see what people are saying but not join in.
