I flag any non-english memes, so they go back into submission, as do many people. I've never heard of anyone complaining about their memes being removed from Featured status because they were not in English. If they did, who'd understand their complaint? it wasn't in English. I think some of the mods are afraid to reject them out of fear that they may be called on for being bigots, although that's the terms of our use, and it doesn't leave a lot of leeway. there's a guy with several alts that every week posts the same damn text over different pictures that I think always gets downvoted back to submitted. He must use them on a blog. but they make no sense.
I had a few memes that had 50+ views before they were featured that I shared as soon as I submitted them. Mods must have thought that with that many views, I was using alts. A friend has the same problem. She gave me the link in an email, I shared, and the posts never featured.
