If you suspect that someone is misleading consumers with illegal tourism grading stars, there are a few things you can do to determine if this is the case:

1. Check the official Tourism Grading Council of South Africa (TGCSA) website to see if the establishment is listed as a graded establishment. If it is not listed, it may be a sign that the establishment is not legally graded.
2. Check the star grading displayed by the establishment against the official TGCSA grading criteria. If the grading is significantly higher than what the criteria specifies, it may be a sign that the establishment is misleading consumers.
3. Check for any official documents, such as a TGCSA certificate or plaque, which should be displayed in a visible location. If these documents are not displayed or appear to be fake, it may be a sign that the establishment is not legally graded.
4. Look for reviews and feedback from previous customers, as they may provide insights into the establishment’s legitimacy and quality. If there are complaints about false grading, it may be a sign that the establishment is misleading consumers.

Contact the TGCSA to report any suspected illegal grading practices. The TGCSA has the authority to investigate and take action against establishments that are found to be misleading consumers.
In conclusion, it is important to do your research and be vigilant when it comes to illegal tourism grading stars. By checking official sources and doing your due diligence, you can ensure that you are supporting legitimate and legally graded establishments. If you suspect any illegal practices, report them to the appropriate authorities.
