Thank you very much for reaching out @marabuzal.

First of all let me ask you a little favour. Lets try to keep this comment section in English please. Despite the fact that we have a considerable Spanish speaking number of members no one from our team speaks it. Besides that, we are an international community. Can you imagine the mess if we all were typing in our own native languages? 🙂

Regarding your questions:
We do not curate single image posts and we might mute it, as stated in our community rules.
Yes, it's a daily contest and you can participate every day.
Cheers!
