I have made what you call a fake scrape or mock scrape before.It is made by using a stick or branch and raking away an area like a buck would paw away the leaves and then he urinates in the scrape.The way to tell a mock scrape from a real scrape would be to look for a branch or branches above the scrape.A buck will usually chew and break some of them off.They call this the licking stick.It is also a way that the buck leaves his scent markings.Also look in the scrape itself for deer tracks and if you find a scrape,take a stick and smooth out the leaves and tracks and check it at a later time for deer sign.
