Mandatory Third-Party Exclusion of Individuals with Gambling Problems in Germany: Data from the OASIS Player Exclusion System

While self-exclusion for individuals who gamble is widely recognized and implemented as an important consumer protection measure worldwide, third-party exclusion, initiated by relatives or gambling providers, is currently only available in a few countries. The aim of this article is to provide a timely descriptive evaluation of the exclusion registry in Germany, where third-party exclusion is mandatory by law, in relation to different types of gambling and the frequency of use by gambling providers. The relevant authority has provided data from licensed providers, broken down by self-exclusion and third-party exclusion. The majority of exclusion requests in 2024 (N = 303,876) were made through self-exclusion. Specifically, 96.8% of all exclusions were initiated by the players themselves, while only 3.2% resulted from third-party requests. The lowest proportions of third-party exclusions were observed in the sectors of gambling halls with German-style slot machines (0.7%), virtual slot machines (1.1%), and online poker (1.5%). The low proportion of third-party exclusions may be due to a conflict of interest, as gambling providers often generate significant revenue from individuals with gambling problems, making this group a lucrative target market. However, preliminary empirical evidence suggests that third-party exclusions have positive effects, showing comparable rates of abstinence and reduced gambling behavior to those who self-exclude. Mandatory third-party exclusions help minimize harm and represent a valuable addition to public health strategies. Nevertheless, further research is needed to expand the limited database, and the low use of third-party exclusions by providers calls for stronger regulatory oversight.
