Btcrea scam?

Hi I got a discord message saying I won 0.2btc with a promocode on btcrea which obviously screams scam. The site actually exists though and has active support and promocode works, there is a 0.01btc deposit necessary before you can make any withdrawal though, again screams scam. I can't find any real info about the site, is the whole thing made just to scam people, very elaborate if so… Has anyone used it or even just heard of it o got the same discord message, fairly sure this isn't real and if it is fake it's the best scam effort I've seen yet…
