This all situation is really stupid, why is it that when I hear of chinese community it's always something like that...from gacha game drama to overwatch to this, I didn't expect this to be the reverse of the Love and deepspace drama.
I do have something to say about the tag change I get the idea but that doesn't really make sense since the goal of the tag is to filter based on content ,you click on them to see what game fit and the gay tag is use for M/M content regardless of the sexuality of it's character.
The LGBT tag is cover all game with queer theme not only game with M/M...basically what I mean is when people are looking for M/M they will use tag like gay to filter game they will not be interest in and they will not necessarily use LGBT because it refer also to non-M/M game....so currently you have zero tag pointing to a M/M game and only your game description does.
Honestly, I think you should do like other M/M and put both gay and LGBT plus I guess add queer and bara, because not putting them is just stopping people from finding your game...
