"If any of your projects are collaborative and have multiple people, please submit the URL that owns the project page." This is exactly what I did. I made two applications, each for each itch.io account because... I have two accounts. The form asks for one itch.io account. I'm disappointed this was interpreted as an attempt to double dip, even though it's perfectly clear if you look at the pages that they both link to me. I'm not exactly trying to hide that.
And for the record, this is the second year in a row this happened. Last year I was told "sorry, we don't have time, apply again next year". The organizers surely should be able to do something to handle cases like this. Having accounts for multiple person projects isn't an uncommon use case.
