→ artist:thedrunkcoyote Metalfoxxx
is his DA account that he hasn't posted to since 2018. In fact, his last journal post is him saying he's abandoning that account to make a new DA page… which hasn't happened yet. Themetalpony
is his tumblr which has also been abandoned since 2018. Tacticalfur
is his FA page, which is still active. His user profile links to Metalfoxxx on DA and Themetalpony on tumblr. Thedrunkcoyote
is his twitter, which is also still active, and has a link to TacticalFur on FA.
Since he's still active on both "Tacticalfur" and "Thedrunkcoyote", either could work as the main tag, with the other being an alias. But I lean towards using "Thedrunkcoyote" as the main tag because that's the account he started most recently, and he seems to be uploading his art slightly earlier on his twitter than on his FA.
