Actually, this method of placing skins allows me to not make these skins as separate works. This means that they will not be deleted due to the fact that they are similar to each other and some may consider this a duplicate.
Also, the presence of several skins in the description does not give me any advantage and I don’t care that most users don’t do this, but prefer to spam duplicates.

And the fact that you consider this unfair does not negate the fact that I do this out of good intentions, so as not to spam with identical works and to make visiting my content gallery comfortable. This is also called following the rules.

Unfair?

I try to combine similar skins into one so that there are no complaints from the moderators, I spend several days and one sleepless night on this. For someone like you to come and ask to remove it JUST BECAUSE YOU DON'T LIKE IT?
Do you know how much new content I could make if I didn't do this? Nobody knows.
Do you have any idea how difficult it is to do something like this about four hundred times?

It’s unfair that you’re asking me to delete something on which I spent a lot of time and effort.

So keep your proposal to yourself.
