The wiki entry for him states:

Possible Alias: TDK, tdk

[...]

Eric is believed to be the aliased artist "TDK" due to striking similarities in their style, though this has never been definitively proven or refuted.

But TDK is aliased to eric_schwartz

What's going on there?

Assuming the wiki page is correct, I'd definitely think an unalias would be the correct thing to do.

I'll base the decision on the following assumptions:

• We don't have enough direct evidence to keep the two aliased.
• Even if they are the same, it's clear that the artist wants to keep them separated.

Therefore, I've deleted the alias and will split up the art like so:

• Anything with a Eric Schwartz/EWS/furafterdark signature, is related to Sabrina Online or that can be found in Eric's galleries should go under eric_schwartz
• Anything with a TDK signature should go under tdk
• Anything else I'll ask Eric about
