It is very odd that anyone would place such limits on functionality on an internet-bound platform.

And a federated one at that! Creating silos like this is... Counter intuitive.

I'm having trouble understanding if this person is representative of flohmarkt or not, but either way, I don't think they understand any of our questions or arguments.

They admin slrpnk.net, no idea of their involvement with flohmarkt.

I think its safe to say they don't understand or don't care about any concerns though, agreed.
