Their are still a few gambling addicts that might attempt going outside just to gamble but hopefully governments is going to close casino or any places that have a crowd to prevent coronavirus.
In most of the countries that got heavily affected by the virus, all casinos are now close. If you see a gambler that still goes outside and by any chance, you learn where they go, you can report the area into the authorities. Maybe they go into an unregulated illegal casino.
These can consider as illegal gambling as they can still operate freely amid the pandemic virus scare.
Help the government by reporting those.
