Aliasing s1120411 → yagi_the_goat
Link to alias

Reason:

"yagi the goat" is the artist's prominent name on Tumblr and Patreon.

EDIT: The tag alias s1120411 -> yagi_the_goat (forum #234050) has been approved by @Rainbow_Dash.

It looks like someone applied this edit to all the posts manually. Yagi's been moving away from the long number string name on other sites, so it became more actively necessary for the tag change. The alias should still go through, since the s1120411 name is still pretty commonly known.
Yagi's other old number string username, s0711108, could also use an alias for the same reasons.
*string not stream, and missed a digit in the wiki link
