"Unfortunately it seems nearly all Criminology PHD's in Europe are based in the UK" - I doubt that. I know someone doing a PhD in criminology in Rotterdam, for example, and from what I've heard it is quite a large group. In Germany, the usual PhD route is still through individual professors, so you won't find many structured PhD programs, particularly in small fields such as criminology. And Alexander Woo's comment is totally on point.

@AnonymousPhysicist thank you, I hope the new link is more stable. The resolution applies to states only, since it clearly states it applies to "all Member States". As I wrote, I assume that most states from the Western world will have implemented the resolution in their national law, which probably will apply to individuals.

@SimonCrase I cannot exclude this possibility, but in approx. 400 projects that I have consulted I was maybe mentioned half a dozen times in the acknowledgements (excluding my actual co-authorships, of course). So it seems to be very unusual to mention me for 2-3 hours of consultation, particularly given that they did not follow my arguments.

@RichardErickson thanks a lot for your answer. I strongly to attend to agree with your view. I actually decided to ask the authors to remove me from the acknowledgement. Maybe I will also contact the journal, but probably no more escalation after that, also considering what others have written here about the status of acknowledgements. I will definitely follow "you might just blacklist the people and refuse to help them ever again." :)

Among these 400 projects, I have very rarely be considered in the acknowledgement, simply because it is very unusual. So I guess there are two possible explanations. Either the authors were very grateful for my consultation (which I doubt, otherwise they would have followed my suggestions, wouldn't they?) or they wanted to make the impression of statistical expertise in their paper. Nevertheless, I am surprised that many people seem to share that perspective of acknowledgement not implying endorsement. That's definitely something that I have came to learn now, and I will consider it.

@user2705196 thanks for the advice, but your suggestion seems quite unrealistic. Statistical consulting is part of my daily routine. In the past 5 years I have consulted more than 400 projects. If I would demand to read each manuscript before submission, I would do barely anything else than reading unpublished paper all day long and probably I would also come across as putting everyone under general suspicion.

@user2705196 the paper is published.
