Yeah, it's a good idea. In fact, I've been thinking about creating a slots review site a lot lately since I think targeting mainstream gamblers is the best way to grow referrals.
If it's not about gambling, I could build the site in no time. However, I still feel a bit paranoid since gambling-related contents are illegal in my country.
One possible solution is using an anonymous domain and hosting service, but it is way more expensive than the regular one. Not sure for a hobby project like this is worth the price.
