Thank you jk, I've figured it out. One of my fav maps is Realms of Valara, published in January 2020, but that's more than 200 maps ago ':-)
So then
If the maps they’ve made are only from this year.
I go to my fav map of 2020, go to the "all" of it's developer, and then have to check if it's first map is actually of 2020. Oops, no, it's from 2019. Next!
Been scrolling trough the maps like this for over 3h. Hope it was worth it!
