The 40 minutes of the presentation before the hack gives a lot more context: there are 2 journalists in addition to this anonymous pink Power Ranger, and they investigated the Nazi network, which is international. And Martha Root (the pink power ranger) was trolling them by creating an account and using LLM. The LLM didn't work properly, the account was blocked for suspicions of being a bot (and maybe for having "= 1 OR 1" as eg. gender), she talked her way out of it, and incredibly the admin that unblocked her asked if she wanted to meet up with him, and the site's founder. She said yes, didn't show up, but used that opportunity to covertly follow them and uncover the founder's identity - the journalists found that it's a 57-year old lady who's never been known in the scene, who was married to a French banker whose parents survived the holocaust, but in the last decade fell into the rabbit hole of white-victimization-theory.

Only one side of the political spectrum routinely resorts to malicious/vexatious behaviour as their modus operandi.

You're exaggerating. Yes, it gives up the "doxxing not OK", but there will often remain a large moral difference between "Alice was accurately doxxed as KKK/Nazi" versus "Bob was accurately doxxed as $X."

There are very few $X which are both worse, plausible, and "the other side."

We also need to ask who is going to care or be convinced. Orwell's The Party does not care about ethical or moral consistency, only power.

Exposing racism? Where is the moral problem?

This isn’t exposing people for being white but for being supremacists.

If they also expose something of the same kund of wrong I see no problem, everything I wouldn’t call doing the same.

That’s like comparing police arresting people with criminals kidnapping people, both do kind of the same: imprison people.

If "Their Side" did the same to innocent people who hadn't declared they are everyone's enemies its a completely different scenario.
