Teams Housekeeping

Does anyone have any hints and tips for maintaining a good level of housekeeping with teams. As projects close, people move on and the need for a team in Workfront is no longer required OR people are creating teams very close to teams already in existence the number of potentially redundant teams in the system rises. Currently people with plan liciences are enabled to create teams and I'd like to keep it that way and not require admin to get involved routinely, however the flip side is Teams can multiply quickly.

Therefore wondering what others have done and if there may even be some reporting tricks we could use to flag potentially redundant teams.
