As a general principle I would say No – with exceptions allowed upon asking staff, and explaining why this is being requested.
Anyone wishing accounts elsewhere can get them easily. If they value what Qoto has to offer, I think it’s reasonable to ask why is a secondary account needed.
And it should have info on it mentioning the other, possibly main account of the user.
Too many accounts already inactive, I would personally clean up older ones, as the numbers don’t reflect the reality of the instance. Pointless, Quality trumps quantity in my books. But that’s for anther day, another topic and discussion, Mary Kondo could help.
