Avoiding predatory websites
A- When purchasing a product online and you are seeing the landing or squeeze page, try to locate any 'contact us' information. If you cannot find any 'contact us' information there or in the web pages, you can be sure that there's no way to ask for your money back, or for help. Avoid doing business with any company with no contact information.
B- When paying, be alert to a landing or squeeze page that says thay they accept clickbank or paypal, but when you are further in the payment process somehow you are not on official pages of either of those companies. You are being either the victim of an outright fraud, or the company wants control of any refund process, or they have been banned from using Clickbank or PayPal.
C- Many products on google searches have headlines that announce person or plan XXXX is a scam, a has been etc. These are not real reviews, only advertising, ignore them.
D- In reading complaints filed with consumer organizations avoid a company that has changed interstate USA addresses constantly, they are probably avoiding the law.
E- Be wary of recently registered companies with Les Vegas, Nevada addresses. Consumer protection laws there are few. Many businesses moved to Nevada for this reason, to avoid being sued.
