No. My old account I submitted three a day. Hell, I had them stockpiled. Got cut back to two a day, then they wouldn't feature them after submitting. Deleted my account when they did that. No, the last submissions were not political, obscene, or personal attacks. No, it's got to be something else.
On my new account, I had 2 a day and, until Thanksgiving, 100% featured. Took 18 hours for the Thanksgiving one to feature, but the second one hasn't, even though it's got 26 views, 2 likes, and 2 comments. Funny thing: later in the the day I saw a similar meme that was created 10 hours after my unfeatuted one.
Go figure.
