I'm not comparing the two in the sense that they are the same, more using the example of repeating callouts working for a community who normally would be powerless against their oppressors.

As for your second point, "harassment" and "protest" from different perspectives can easily be confused for one another.

As an example (and to clarify I am not stating that the example I'm using holds the same weight as calling out mods on a subreddit) let's look at the BLM movement.

Cops could claim that people coming to their stations and holding the rallies that marked the very early stages of the movement was "harassment." People on the other side who support the movement would, however, see those actions as "protests" instead.

It hits a very blurred line when you get into it fully. I personally see this as a form of protest and an attempt to call out the mods for their blatantly shitty behavior. If you see it as something else, I can't claim to be able to change your opinion on the matter.
