The fiverr ToS link is missing an ‘h’ in the http. Besides that and the bit-ly, it looks very professional and real. Did you look at the videoask link? I’m not going to enter it, myself, but that’s the only other thing that seems out of place, but I know Fiverr staff do use other platforms/services if they need to.
CS is taking upward of 10 days to reply, and I would hate for you to miss out. But on the other hand, why is there a time-limit in the first place? If Fiverr Business is ‘invite-only’ and this is an
on-boarding thing, then why couldn’t you join the next group of individuals to get the invite?
