If the memorial in question is a direct relative within four generations (siblings, parents, grandparents, and great-grandparents) to you and the original submitter is not direct family, then they must transfer the memorial. If they refuse to transfer your relative to you, contact [email protected] and we will work on it for you.
Please remember that there are thousands of contributors to Find A Grave, and it is highly likely that some of those contributors will actually be part of your family tree and share some of your ancestors.
Also, the goal is not to "own" every memorial of those to whom you are related. The ultimate goal is to have meaningful, accurate memorials that honor those who have passed away, regardless of who created the memorial or who maintains it.
