All of you are afraid to give negative trust to these user's because they are high rank and reputable. What a shame.
Am i missing something here? What untrustworthy behavior have Little Mouse and RapTarX potrayed that you think should get them tagged. Sincerely even if the accounts are alts, it's not a crime to have alts unless you have caught them have engaging in shady activities like cheating in signature campaigns.
Deception, deceptive behavior - the inherent feature of untrustworthy behavior. Please stop the apology culture, where no remorse is shown for wrongdoing.
Little Mouse I am also considering flagging as he has misrepresented himself to his past clients i.e. defrauded them.

Where is the crime here? Let's say both are owned by one person (however the evedence is too weak). One can have multi accounts.
Besides the existing, many any potential errors here as well, you just have to think. e.g. if one of the accounts was gained by account trading, then both accounts need to be flagged.
