Just... hold off for a moment replacing them if you can. An approver will get to yours in due time. In the meantime, @BrokenEagle98 let's not tag them "tumblr samples" just yet, albeit you can comment that link in for now.
Replacing samples is currently a fairly complicated issue since it inflates the deletion count for users, and opens up the possibility for stealing credit from other users if done outside of the post replacement function. Currently, we don't have any sort of regular cleanup job for these, so it's a really, really strange situation.
I'm fine with replacing my own uploads, since I took the time tagging and commenting all these myself (a lot of the Matilda Vin tumblr posts had creation videos and associated comments from me pointing out their youtube videos). I really don't want to give away all credit to an approver for my effort. At this point are we simply not allowed to manually re-upload and flag, as before?
