Impressumspflicht only applies for commercial interests. If you are a company informing or even selling something, if you are an influencer making money of yourself, or even if you just have ads on your Pokemon-fanpage, then it counts as commercial interest.

But I don't see any direct monetary value on this site at the moment. There is not even a reputation-gain, as there is no personal information. So Impressumspflicht would not apply.
