Hi and welcome! This is not really a skatepark, it's a pump track

It's already added. This point can be removed.

It's correct though that you've removed the name. If it a skatepark needed here, we shouldn't add description and types of features into names.

About your other edit with a water tap, it's already added too and with better tagging as drinking water, not just unknown tap with unknown water quality. It's added 8 days ago, so you probably can't see it in OrganicMaps. So your water tap can be removed too.
