I went back through the TOS for the site where I posted the video, and it turns out that they don’t allow external URLs to be mentioned in their videos. I don’t know if this was the reason my video was flagged for review or not, but all the same, I’ve deleted the video since I did include links to both of my tumblrs in it.
I’m still going to wait until I hear back on the support ticket I opened before I post the video again, though, just in case there was another issue with the video. (Again, if the person who flagged the video is reading this, please message me so I can try to resolve whatever problems you have.)
On what may be a related subject, a recent perusal of my blog’s archives revealed that a LOT of the MyVideo videos I linked to last year have been taken down. I couldn’t tell why because the site’s messages are all in German, but I deleted the posts from my blog just to clear up dead space. Still, it may be that a lot of those videos should never have been posted on MyVideo in the first place. (This is the reason I’ve stopped linking to videos here recently, except for things like Nikki Nefarious’ YouTube videos where it’s clear that the producer is posting them.)
