it reads:
I suggest making the tag something that is not pronounced the same as Deltarune. The reason being because a lot of non-native English speakers would easily mix up UNDERTALE and UNDERTAIL and even though that name is funny in English it was not the best choice in retrospect.
So I suggest using something that has a clearly different pronunciation. So at least “deltaruined” instead of “deltaruin.”
it’s probably safe enough to assume this is legitimate (and even if not, it’s still a good idea). you know what that means: tag appropriately, or blacklist if your name is yellow and you want to be SPARED.
