Curiously, if you look for "geramond verlag betrugsmasche", or "verlagshaus24 betrugsmasche", it will now tell you that
there are no indications it is a scam, but "significant organizational problems and extremely bad customer support lead to (list of bad experiences)".
The result I get has an entire section dedicated to scammers using the company name. The only links in that section go to a wikipedia page that doesn't mention any scams and a police help page that doesn't mention the company.
Do the links actually support the statements? When I've followed such links, it's generally been a roll of the dice on whether they do support the AI's statements.
Yes. The links are to isolated threads on a rail (model) forums (apparently, this publisher markets books/magazines related to railway models).
It's hard to see if the individual complaints really support a general problem, or if this simply the only result that talks about "scam + business-name". Probably, the latter.
The same problem happens on google search, if you look "<obscure false fact>", you'll get pages mentioning that false fact. If you fall into the trap of confirmation bias, it leads you to think the false fact is in true.
