Recently, a new Member was Posting actively on the German board and I was surprised, that out of nowhere a new Account was active, which wasn't seen before.
I checked his Post history and no surprise, he was previously active in the Croation and Serbian board, where he made many previous posts. Recently, the Account switched to German, which seems to be his new mother language.

In addition, he is sigspamming the German Forum with unhelpful or even wrong statements, like that Ethereum would be a token, not a coin but Ethereum is a coin.
