To me, on a personal basis it depends on :
1. Is the person who would be the target of the action someone who's involved in socio-political campaigning and therefore choosing to be in the public eye.
2. Do they themselves approve of such underhanded tactics used against people who they consider "acceptable targets".
3. Does it open parties that aren't responsible for the person's behavior(for example underage kids, their parents, etc.) for unnecessary harassment and is it likely that those persons would get harassed.
4. (Regarding this site) : Does it add anything worthwhile to the discussion / lead to good content?
Personally, I view most of public doxing largely pointless since if there's anything worthwhile that the dox can do, people who mine for the content about Lolcows can utilize them privately, while displaying their phone numbers and street addresses doesn't imho really add to the "content" a lot of the time. It's mostly there as a resource for people who are autistic enough to

them. The idea of getting in people's face with the whole "We got your dox, whatcha gonna do!"-thing as far as this website is concerned isn't a simple issue - it can definitely be a tool when dealing with quasi-lolcow-y entities such as the people who attack this site with similar methods, but when it comes to actual, funny Lolcows, it's rarely adding anything relevant and gives said Lolcow an almost legitimate reason to get upset about us documenting them when people are talking about a harmless web cartoonist or spergy internet reviewer as if they were the spawn of Satan while displaying their phone number in the op.
Though, my point of view is kinda skewed because I personally don't like to follow Lolcows that are unpleasant, so for example it's not taking the GamerGate tranny shenanigans and how doxing plays into those kind of cows into account so take from that what you will.
