Hello, i actually beated the world record. The time was about 4:50, but i still don’t have any answer to how i can post something with dropbox. How do i share something with dropbox?

i'm sorry for not getting a good link (i mean i literally posted a rickroll) but i did not have a youtube account. what should i do if i don't have a youtube or twich account to literally post the proof? also, did i get banned for rickrolling? hope i'll see some response.
