The Myers-Briggs Type Indicator® is a trademarked tool. There are a number of companies that offer look-alike tests, and they may even use the Myers-Briggs name or something similar to it to create confusion. They are trying to deceive people into thinking that they are taking the Myers-Briggs®, when you’re being offered something else. (This is true of the DiSC, also, by the way, so beware!). My online assessment center offers the trademarked Myers-Briggs® and it is licensed and maintained by the Consulting Psychologists Press, the publisher of the MBTI®.
