I’m a bit afraid to make new posts because a lot of mine were removed, but I believe I had around 3-4 posts of webms from Taimanin Asagi which were removed for watermarks that were not present

I uploaded around 7, and I think only three had watermarks.

From what I can see, 5 videos had watermarks and 1 was deleted for scat.

I believe only 3 of those removed for watermarks actually had watermarks. I’m not sure if I should just reupload those three or what?

You should not reupload content that was deleted, if you think it was deleted in error than you should make a request for review

All of your uploads deleted for watermarks have very easily noticeable HentaiHaven.xxx watermarks in the corners. In one of them, the video itself is blurry so the watermark can't be easily read, but a watermark is a watermark even if it isn't legible. In fact, even if you cover up a third-party watermark with a solid color bar, that solid color bar is itself a watermark.
