In the latter case, I think it might be feasible to prevent upvotes from being counted multiple times if the username is identical on different instances, since upvotes are public. Is there already a mechanism to do this?
Also, isn’t it much more common in the Fediverse than on central platforms for the same user to have multiple accounts with different usernames? This seems likely to me, if only because popular usernames may already be taken on a given instance. In this case it seems to me hardly possible to prevent double counting. I suppose this would only be possible if the different instances would log IP addresses and share this information with other instances. That doesn’t seem desirable to me at all, and probably wouldn’t be legal, at least in Europe, because of the GDPR. Are there other possibilities? Cookies?
Please excuse the maybe stupid questions - I’m new here and not very good at finding info on my own yet…
Simple solution, let us see who upvotes a post. Kind of like how Facebook lets you see you liked your post. It wouldn’t prevent posts from getting brigaded with bot votes, but it would let us see that it is happening. Oh 1k votes on this post? But half of them are from dude@differentinstance.net? Probably bot manipulation.
If you’re on kbin, click on more and then activity. You’ll see who boosted, who liked and who down voted said post or comment
On the user profile you can see which posts a user has upvoted. But if you could see it directly on a particular post, it would be pretty helpful, I guess.
