Idk How To Tag This Uhh - Tumblr Posts

Okay so idk how else to do this besides asking Tumblr users themselves (at least some of em anyway) but I'm wondering if there's a,,, correct way? To post content? I'm speaking more in terms of consideration for other people or parties when referencing them in my posts because I've started to overthink what I'm doing and now need guidance 🙃.

I draw a Lotta fanart and talk about the peice for a bit in my posts but I also usually tag the creator of the content I'm making art of because 1) let's people find out more about what I'm drawing and 2) so the creator can see the art cuz I think they would appreciate it, though this is a presumptuous notion on my part.

So just like... if yall can give me a crash course on how to properly do this kinda stuff please let me know because I cannot keep talking myself I circles about it forever unfortunately.
