If I was surfing through your site and decided to click out, only to have the page blocked, I would immediately close your site and never return.
I might also send you an email to thank you for taking away my right to read and learn freely on the internet.
Presumably you would use geotargeting because you assume that, by sending me to an online casino website, I am going to break a law. It isn’t your job to make that decision. Don’t assume. Enforcing the law is up to my bank, and it is up to the online casino. There is no need for you to get involved in that at all.
As an American, I do not appreciate having material censored — especially since it is not illegal to simply READ the content on an online casino landing page. By censoring content like this, you are no better than the Republican assholes who would love nothing more than to eliminate the right to free speech and free expression in the USA — aka The First Amendment.
There is a reason the First Amendment is the FIRST Amendment. Freedom of speech was the most important issue when the founding fathers wrote the Bill of Rights, and it remains the most important issue today. If we lose the right to express ourselves freely; if we lose the right to read what we want; if we start banning books from libraries (or if we start banning pages from the internet), then we are no better than China or Cuba.
Geotargeting has advantages, but it should absolutely not be used to censor anything.
Regarding lawyers — I believe many people have received extremely bad advice in recent weeks. Most lawyers will take the path of least resistance by telling you to “play it safe.” They’d rather hand out conservative (but bad) advice, collect their fee, and send you on your way, hoping never to hear from you again. Most lawyers won’t care that your point of view might actually prevail in a court of law. He doesn’t care that you might go out and close down your profitable business because of his advice. Nope. Most lawyers are bloodsuckers, and many of them care only about how to make the most amount of money with the least path of resistance.
