It is the price for properly tagging the game, we could be seeing a shitstorm of complaints from people who find the scene and don't like the content type instead. I've been seeing it on a lot of threads lately since a ton of games containing NTR were uploaded recently.
NTR is a group term for several related fetishes, the main one at fault for the reputation for shitstorms on here being Netorare. There is also Netori and Netorase, which are where the PC does the stealing or where the PC is actively involved in the girl having relations with another respectively. There is also historical evidence, by which I mean on this site, of use for both Netorare and Netori in the tags. A good 10% of NTR tagged games on here involve Netori, the other 90% being Netorare or Netorase, not sure how much is Netorase as I actually haven't seen any. I mean, we could always ask the mods to see what they think, but now isn't quite the time as the content in question isn't in yet, it's barely started. I would suggest we wait until it is actually added, then we could see. I don't know how we should go about it if we go for it, though. Whether we should go through the actual report process or just find a mod and message them since we aren't definitively sure on whether the tag is appropriate.
