I feel like gambling can be allowed to continue advertising but it needs to be advertised similarly to plain packaged cigarettes, where all they can offer is white text on black background with a link to the website for those who choose to partake. Take away the glamour and allure of ‘winning big’ and ‘bet with your mates’. Yes there are whole industries that might not be able to exist if gambling declines (horse & dog racing etc.) but this is probably a positive outcome.

I’ve found most registrars will at least list the price after the first year. So you should be able to buy it for $0.01 with the clear knowledge of the normal yearly price to expect. I’ve used Cloudflare for registration and they’re pretty good, only issue was some TLDs that weren’t supported by them. PorkBun seems to get a good review. I personally use a local registrar who offers TLDs local to my country.
