While I personally have nothing against that, you should probably question yourself why do you want to join a contest on a platform you're not interested in joining, or reading said contest rules.
I think I was a bit confused about the rules, at the beginning. For some reason I thought the contest is held here. But anyway, thank you for explaining things. I joined Discord and I posted there my submission.
I personally don't have anything against @GazetaBitcoin joining the contest. The more the merrier 
Hehe, thank you for your support, Rikafip! I just posted my submission there. I'd also like to congratulate you for your extremely well looking pizzas! Man, you seem to be an expert of this domain! You have my respect for that!
