The tag alias #56231 silverteam2017 -> darkshadow has been rejected.

Reason: Alias from FA username to e621 username.

You are presumably not referring to the user named DarkShadow, who hasn't been seen in ten years, but instead the one named DarkShadow 2017, who uploaded all of the images with those tags: ~silverteam2017 ~darkshadow -user:DarkShadow_2017 The origin of the silverteam2017 tag appears to be that, when that user uploaded images without an artist name, they were later tagged by a user named Landrius, who also added FA sources, with the FA username.

It seems reasonable that all the images DarkShadow_2017 has posted are their own art, but I can't find any links between the Furaffinity or Inkbunny accounts.
