I have only one account, to make that clear :)
HaHa, we are all hypocrites. :D
It really depends on which perspective you take, that of one individual (yourself) or that of many others. Multiple accounts are an impossibility in real life because you only have one body with which to do business and actions. In the virtual world, however, such a thing is possible. Of course, you know that.
Box of Pandora?
Since such a thing is now possible and there is no way to prevent it, unless you make the entry level so high that, for example, in order to register an account, you either require verification via an identity document or a purchase for a large sum (which would still not prevent someone with a lot of money from buying multiple accounts). Usually, the reason for pseudonyms is that, for example, an author was politically persecuted and therefore had to do without his or her real name. Anonymity in a world where a person had to fear for his life or his financial stability and reputation is important. Keyword "whistleblower".
But the fact that one maintains several accounts on Hive is probably more of a fun element or an experiment on the part of the person acting. Or, unfortunately, also to enrich oneself personally through circle voting without having to rely on other users. Personally, I would consider it too much energy expenditure to maintain more than one account.
The problem with multiple fake accounts is that it can distort and influence processes in such a way that, for example, opinion-forming online can be extremely manipulated. Just imagine that a single person creates hundreds of accounts and then uses them to manipulate an election. Bot farms are an expression of this phenomenon. From my point of view, it is control fanatics who use something like this. Or fools who want to shake up the world. Of course, it is the fools who often point out a flaw in the system.
Therefore, the election of witnesses is not completely secure here either. Who wants to know how many individuals cast their vote through multiple accounts? Question still remains, if the opposite forces (also holding multiple accounts) still balance things out.
Lord Voldemort, however, finally failed in cutting his soul into seven pieces :)
