We can not know this from the screenshoot alone. The membership itself is mentioned.

Maybe the fee is mentioned on a other screen.

As far as i renember it is not really "illegal",but the contract is invalid.

I think the law in Germany is very specific in how obvious it has to be what is being purchased and what it costs. Some mention somewhere in the fine print is certainly not enough. I've heard they even specify texts for the buttons, it has to be something like "buy now" to make it clear that the action will lead to costs.

I didn't check what followed, they might well have mentioned the specifics clearly on a follow up page. My point was simply that this is already far clearer than the scammy .com site.
