"dislike attacking" is also a very loaded term. Technically it's only referring to the intent of the dislike, but it strongly implies that dislike cause harm.

The opening paragraph seems to equate these "dislike attacks" with "creator harassment" but I'm not seeing any data on dislike constituting a form of harassment.

Don't get me wrong, creators suffer a LOT of online harassment. I'm just very unconvinced dislike buttons are a primary tool of harassers.
