Doesn't surprise me. There are a lot of very poorly written comps out there. They're after your instagram handle, so I'm guessing maybe you are supposed to post photos on your account and probably tag them somehow, but it's a mess at the moment.

Note: I'm a little confused with this comp. It only says to fill out the survey, but there are indications of needing to provide RAW photo files later on. I've put as Other Skill just in case.
WIN the new NIKON Z5II.
Take your photography and videography up a notch with the Z5II full-frame advantage.
Complete the survey before 11:59pm on Thursday 8th of May, 2025 for your chance to win the new Nikon Z5II.
Given that in the '6. Entry Requirements' section of T&Cs they skipped 6.3, 6.4, 6.6, 6.7 and added a 7.2. I am going to guess they were just copy pasting info from a previous comp.
