"Spoiler/Censored" image feature for submissions w/o sensitive content
I think it would be cool if artists had the option to "spoiler" (basically, enable the blur filter) a submission even if it does not contain sensitive content, and they should be able to set a duration for the filter.
For example, let's say I'm submitting an art piece that might contain spoilers for a comic page that is coming out in 3 days. I can "spoiler" the image, enter custom reason "comic spoilers", and set it for 3 days. This will allow my followers who are reading my comic to choose not to view the spoiler, but followers who do not care about spoilers can view the artwork. Additionally, the spoiler will naturally fall off the image after 3 days (or whatever time-frame the artists sets) without the artist having to go back and manually change it.
This could also have other applications, such as for people drawing fanart of newly-released media.
