Actually I am not clear what is wrong with this all account.  I can't find any connection between them. Sent merit it dose not prove that they are connected. As well as theyoungmillionaire is an potential use with good reputation.
See here on top merit user list :

If you have personal problem with them solve it personally . Don't expose on bitcointalk.
I think you should lock this thread due to there is no any evidence of connected account or mass merit.
