Not that I know of. Typically if you take an avatar that is in use by someone, someone will let you know. Also you can drop into chat and ask if a model is being used as an Avatar. Some people know scary amounts of info about who is using what model, so they might be able to give you a good idea if the one you are looking into using is already in play.
