| The legal argument appears to be: 1. There have been breaches of data protection law (GDPR as implemented in the Data Protection Act 2018), e.g. players did not consent to data transfer, the data isn't accurate, etc. and it's done on a commercial basis. 2. These breaches were injurious to the economic prospects of the affected players and therefore damages should be awarded. I would imagine that the cause of action will be the tort of negligence against whoever sold the data on, and/or the gaming, betting, and data-processing companies. This is because they arguably had a duty of care to the players, the duty was breached, and the players suffered some harm -- based solely on the facts in this article. Regarding personal compilation of statistics, that's fine - there's an exemption for activities of a purely personal nature in the GDPR - which is why you wouldn't get caught, but commercial exploitation of the data falls outside of that. |
Here, specifically, GDPR prescribes exemptions for journalism: https://gdpr.eu/article-85-right-to-freedom-of-expression-an...
There are probably other exemptions that would apply for innocuous activity freely done in public, with the explicit understanding that it would be filmed.
