So [artist:SeriousB](/search?q=artist%3Aseriousb) is now also DinesOnX.
The Artist keep the old Art on the old Account, not transfering it on the new so maybe both Names should stay.
Maybe with an Info in the Tag artist:SeriousB for the new and in the Tag artist:DinesOnX an info on the old Source Accounts.
Of course only if the Artist still draw MLP Art (on the new Account are just a few Artworks so far, none MLP).
