Um... Netori is also a version of NTR. That's the sole reason some VN's here get lot's of questions about NTR.
Most people (myself included) have no problem with Netori at all. A big chunk of them (also me included) also have no problem with sharing (Netorase). It's when the real hard core of NTR (Netorare) is in a VN, lot's of people (again - myself included) don't like that.
The problem with the NTR tag, is that it's MUCH to generic. It would be far more easy if that tag was dropped and the more specific tags (Netori, Netorase, Netorare) where used. It would lead to a lot less questions in the VN threads (especially if it would be marked as avoidable or unavoidable).
I still can't believe that netorare took the term NTR and rolled with it. Like you mentioned, there are three words so how the hell aren't they NTR for
Ne-

re?? Some places tag netori as 'NTR', some places tag it 'cheating' and some places don't tag it at all... And any places that tag things 'netori' when it's netorare or netorase should be considered traitors against all lewd content. Same goes for developers who make games with both perspectives, netori and netorare, and don't give us an option to disable the netorare perspective. Why is it so god damn often a "reward" for going trough the cucs story that we get the perspective we want to see?
Nothing wrong with liking NTR of any kind, but it's pretty ironic how often us netori enjoyers get cucked by other NTR fans in terms of amount of content and trying to find it. Sad thing is, if it was the other way around, both parties would be getting what they want.
