Yes, I know that he had several accounts, and in each one he developed different topics, I don't think that is wrong. The detail or inconvenience I see is when someone makes use of several accounts pretending to be someone different in each one. For example, in the case of my community, which has a not very large support capacity with votes, supporting two or three publications of the same user, from different accounts is where the limitation would be. Because we would subtract the possibility of supporting other users by supporting only one.
Thank you very much for your support.
