Pretty common strategy. Facebook owns facebok.com, Apple owns aple.com, Google owns gogle.com, etc. Scammers try to buy domains that sound or type similar to legitimate companies (practice known as "typosquatting") and use this to fool customers into thinking they're on the real website. One easy way to combat this is to just pay up and buy all the domains that are "closely typed" to your real one and have them all redirect to your property.
