I get what you guys are saying, and I mostly agree, but disagree slightly about what it would take for his stans to completely turn on him. As long as Corpse isn't revoltingly ugly, obese, and there are no other outside details (like being a groomer or something), I just do not see his popularity taking a huge loss from a face reveal when his voice is his main bread and butter.
If I'm wrong, I'll eat crow. Either way, I imagine it won't be much longer before his real identity is leaked, there's just too many people wanting to know who he is.
