Controversial opinion: stuff like dissolving with snuff shouldn't count as transformation. You wouldn't call a burger you ate an hour ago "transforming" and in vore comics it's not "transforming" when you see skin melt away.
On a different website there's a different person who posts stuff in the transformation tag and it's stuff like this where it's like "oh we shot a beam and it atomized this person killing her instantly" or "as an experiment she took a shower and the water disintegrated her on contact and she went down the drain" and it is frustrating.
