User: Little Mouse - Currently a DT member (as far as I see)
Not a DT member. As far as I know, RapTarX is from India and Little Mouse is from Bangladesh. Though the alleged post and the followup investigation raises doubts, I don't think it's appropriate to red tag the accounts.
The entire point of having an alt in most cases is to segregate the identities and provide anonymity. Trying to hide the fact that it is an alt alone is not evidence of any illicit activity.
You mean that I am allowed to use a second account to use as another official member, I can use two accounts to participate in different signature campaigns to earn decent money 
This sounds great! And when I opened a campaign management service, I could open with both accounts to increase my chances of competing with others without anyone knowing Go ahead!I was just kidding
I wouldn't agree with a person having alt accounts and acting like different persons. But I guess you are allowed to earn with both the signature space of your Main account and Alt account from different sources.
Example: LoyceV and his alt, LoyceMobile
- LoyceV earning through Chipmixer Signature Campaign.
- LoyceMobile accepting Bitcoin Lightning for advertising in a small portion of his Signature.
So, if the above example is Ok for everyone here, then it's fine for others too as long as they don't scam/cheat anyone.
