Domain name front running

Domain name front running is like if someone was given the first chance to buy something before anyone else knew it was for sale. Imagine that you were in a grocery store and you heard someone say, "Grapes are on sale next week." You would rush to the store early and be the only one to buy grapes since no one else knew they were for sale yet. Domain name front running is the same idea, but for websites. It is when someone hears that a website address is going to be available, so they quickly buy the address before anyone else knows it is for sale. That way, they can get the address and make money by selling it to someone else who really wanted it.
