I keep trying to submit a video but I keep getting "sorry, we couldn't verify that you're a human". I fill in the answers correctly of course, it's basic first grade math like "what is twenty-nine minus thirteen?" and when I type in "sixteen" it send me to the "see if it's a duplicate" page (it's not a duplicate), I click that it's okay to submit but I get looped back to the submit page with "sorry, we couldn't verify that you're a human". I tried numerical answers but it won't even accept those. Why am I being sent in an infinite loop?

Additional info: I just signed up today, was there a waiting period I missed in the terms and conditions that perhaps I overlooked before I'm allowed to post?
