The best we can do is to activate all privacy options. And not send out any messages with the accounts. Basically an inert account. No-one will know how to find it, and even IF it will take a long time to do so. Use a dummy email account as well to create the dummy social accounts.Is it possible to hide those dummy accounts from the public. I wouldn't want a new designed logo, that hasn't been approved by the client yet to be traceable or seen by anyone
