Doesn't post their own art.
Might be aling?
If E621 User:HoloceadianSaphira is holocesaphira (which might be the case, given the lack of source on post #4900871) then they tagged post #4900879 as being drawn by ‘aling’ when the “source for that image”:[https://x.com/SaphiraButNSFW/status/1779479196663791632] says it’s drawn by a Twitter user with the name of this tag, “@ l3534795389328“
But it’s only one instance.
