Things like "I think it might be a scam" fall under the First Amendment of the United States Constitution. It doesn't matter if the person writing it is in another country, this website is on servers in the USA and those posting here are effectively making their speech under the protective umbrella of US law. Unless someone flat out states that something IS a scam with no foundation for that belief, no violation has occurred.First, it is extremely irresponsible to write about things of which you have no knowledge, especially on the internet. Comments like "I think it might be a scam" may fall under Federal Internet Harrassment laws when delivered in the context of a website that is meant to review services. I'd caution against expressing/intimating contempt before one investigates.
