I support what cabron has said, this days, alot of things are changing really fast, it's not just in the tech industry or market, but some casinos are also changing rules and updating their terms of service sometimes without even letting their customers know, running a review site will require you not just depend on what people say about a casino, but it will require you to use a casino yourself, have your own experience with the casino, this will help you write better and honest reviews.
And I did also say that, most online gambling casino reviewers started just as you, made good promises about not ever collecting money from any casino to write a good review for the casino when in reality, such casino doesn't deserve a good review, but after starting, the first casino approaches the review site owner with thousands of dollars, money the review site owner may possibly have never seen or touched in his life, and then, they accept the offer and deviate from their promise, this is why I personally never trust new review site owners coming to make such promises as you just made, human beings can't be trusted, they are very frigile and can bend at any slight opportunity.
Now, talking about casinos where or that are VPN friendly, you have to specify the type of VPN, is it free or paid VPN? For both are not the same.
I plan to check out complaints every day for 10 casinos max (both here and on Casino Guru, which I think is pretty fair from my own experience). I'll be looking for specific problems like:
1. A casino not paying someone because they're from a certain country.
2. A casino asking for proof of address and proof of income.
3. Withdrawal more than 24 hours (unless it's about limits).
This is going to be a small project on the side for me because I'm not really into doing SEO stuff. However, I always look for new casinos to try, since I tend to block myself in casinos where I don't win anything after a while.
So do you know about good casinos that are okay with using VPNs?
ps what is the difference between free and paid VPN except choice of countries?
Regardless what you may think, have it at the back of your mind that casino have the sole right to do whatever their wishes and what look like a rule today may not be effective in the next day and for that you have to be constantly update with how you collect those informations and updating them on your surpose site.
So you have to prepare to put all the necessary mechanisms in place that will put you an edge with update information and rules of those casino as the change's, this could be possible if you have a bot that do the checks.
I know how to do that monitoring. But I'll review trusted casinos. I'm OK with new brands, but recommend it to others is too responsible. As some people here told me that Crashino at start was good casino, but now they withdraw like 3 days (I experienced that).
