@Roseluck I fear there might be a confusion on the nature/use of DNPs and takedowns, though maybe I'm misunderstanding things.
Making the aliases you're requesting is easy, and the tags being aliased will instantly be replace with the new replacement.
Depending on what you intend to do, a DNP/takedown request is not necessary. I.e., you do not need to re-upload the images with a change of tags, you can just edit the tags or request the aliases you need, without submitting a DNP or a Takedown Request.
In other words, please only submit a DNP request if you want to place restrictions on uploads of your art, for example:
— Restrict who can edit your art
— Restrict who can upload you art
— Restrict all uploads of your art
— Restrict all edits of your art
— Restrict the upload of privileged art (restricting Patreon milestones or rewards for example)
— Other restrictions
of the upload of your art that I may be forgetting.
Also, please only submit a Takedown Request if:
— You're the owner of the art/picture being reported and you want it to be removed from our site.
— If you just want a change of tags or aliases, a Takedown Request is overkill, please edit the tags or request the changes necessary.
I hope that was helpful. I'll handle the aliases and the miss-link now.
