Considering the site itself is an illegal archive of websites, I think its obvious most of us don't treat what's 'legal' as a guide to whats 'moral'.

Harassment an doxing are both illegal.

Doxxing is illegal? I am against it but if it's republishing public info I don't think it can be illegal in the US unless there is an intent element.

The blog author is in Finland, so it's covered by the Article 8 right to privacy of the ECHR. The exact implementation is country dependent, I don't know how it works in Finland but in the UK we just extended the common law tort of "Breach of confidence" to it.

That is very surprising to me. As far as I know, in Finland details of your income are publicly available, but someone reposting publicly available information is illegal.
