There doesn't seem to be anyone else making art under name of Zapor.

a) There is someone else using Zapor username at DA , but they haven't uploaded any art, and have been a member for 12 years ... so probably are not an artist.

b) There is a Zapor username at Twitter (but "Tweets are protected." and avatar & banner are twitter-default so probably NOT an artist's account)
While could be an alt account of Zapor666 (since Twitter location of both accounts says location is "Russia"), they are probably different people as there six years difference between when each Twitter account created and Twitter Zapor's "Tweets are protected", while Zapor666's tweets are public.

EDIT: alternative to alising zapor -> zapor666,
is zapor -> zapor_(disambiguation), in case it turns out there is another artist named Zapor ... or a Slovenian tags with zapor instead of prison (zapor is apparently Slovene for prison )

EDIT: The tag alias zapor -> zapor666 (forum #272816) has been approved by @bitWolfy.
