According to https://www.fflogs.com/help/hidingcharacters

Why should the everyday common player be expected to do that do for a feature not officially supported by SE?
On principle I absolutely agree with you in this regard. It might not be asking much of a player, but I feel it should not be asking at all. No one should have to research potentially esoteric rule-sets of third party tools just to maintain their knowledge or consent over publications of information including them that would otherwise be indistinguishable from publications they, themselves, produced.

I don't think it's a major concern, as I haven't even once seen harassment based upon tools like fflogs, but on principle, I absolutely agree.

But as for other concerns you've mentioned as to harassment and countermeasures therefore, no countermeasures are entirely "free of cost", even if not at direct cost to the game experience, as they still cost development time at the expense of some other, likely more warranted, creation.
