Jeez everyone is arguing about NTR this and NTR that. People there are TAGS for a reason. You want NTR ? Then go check the NTR tags and leave developers do their thing and us simple people to discuss non NTR content simple as that.
If you ever wondered why people aren't asking if this game is made in Unity all the time I can tell you.
The unity tag is credible.
The NTR tag in its current state is not only not credible because people don't know the definition, but also because devs often make it avoidable as not everyone is a fan of it.
Ergo, it being tagged as NTR or not doesn't really matter. People will and should still ask.
This will not change until the sorry state the tag is in is fixed. Either by fleshing out the definition or making it easier to make a tag as "avoidable" when tagging.
Regarding avoidable tags you could have a box you could tick next to each tag while editing the tags.
Ticking it could make the tag appear like this:
...(notice the outline) instead of appearing like a normal tag. Along with every other avoidable tag you feel it's necessary to mention.
Then there's the problem that NTR definition is basically a mish mash of netorare and netorase that people sometimes use for netori as well.(currently netori is completely undefined, no tag defines it)
Adding those 3 separately would be a huge help. This is an adult site with lots of Japanese content, people should know what they mean, either to seek them out or avoid them.
Adding a tooltip to each tag when mousing over them wouldn't be bad either. Then those who aren't completely familiar could get familar fast instead of seeking out a thread they may not know exists:

All of this is why you have a problem.
