It is really important that you have diversification on your team, especially when it comes to cleaning contents. This job takes someone with organization, precision, attention to detail, flexibility to jump from one thing to another, patience, problem solving skills and follow through, to name a few. The chances of you finding all of these traits or skills in one type of personality is pretty slim, if not impossible.
What you need then is to have a diversified team made up of people with a variety of action modes and skill sets to effectively and efficiently handle your contents cleaning.
