Noise reduction

BUR #4503 has been rejected.

nuke noise_reduction

I think, unnecessary tag. Small post count (51).
I ask in forum #179433 about this tag, but users not interested in discussing the tag.
At the same time, users who used this tag upload posts less than a day ago.

It's a useful tag to determine whether a post was altered via waifu2x and similar.

Wouldn't the upscaled or waifu2x tags be more appropriate for that?

Not all noise-reduced pictures are upscaled and you can do noise reduction via photoshop or similar software too.
