I think that the OP will not be offended if he receives a statement in the trust that he is someone's alternative account, as was the case with the PytagoraZ account.
I've always assumed that an alternative account that wants to masquerade as a newbie will be more modest, supposedly not inciting people to speculate about its true appearance and origin.
But yes, alternate accounts are allowed, and given one neutral or negative tag, beginners will create a new one with a clear conscience.
Not a problem, right, OP?
