This happens at every gambling company in regulated markets like the US or Europe.

For comparison, there are offline casinos who use targeted adverts saying that they do not comply with regulators, and their adverts are designed in such a way as to appeal to people with gambling addiction (usually showing some kind of live play, which is banned in every regulated market afaik).

You can be sceptical of the motives of individuals but there are very strong corporate incentives from state regulators (in the US, particularly those with physical casinos).
