Hello @geekgirl,

Thank you so much for bringing your concerns into the discussion!

They should be free to upvote each other, it is their SP.

Yes, you are absolutely right! The use of voting power is up to the owner, no discussions! One may discuss the economic effects of such behavior, but still, everyone is free to use their voting power as they see fit.

Now in this case though, there is more at play than just self voting. I'd even like to add, this wasn't actually real self-voting if we accept the authenticity of the two involved accounts being run by spouses.

So what's the problem about?

Please look at the Lady Diana post this case started with. A single post with a few images from the web, followed by dozens of nested self-replying comments with another single image in each. This wonderful arrangement exist in not only the linked post, but a many others, too.

The issue is not so much the fact that the 2 accounts linked to this behavior are using 100% voting power exclusively on themselves reciprocally. The issue is the spam and obfuscation scheme that is used here.

I would not want to stop anyone from openly self-voting exclusively, be my guest, be selfish and counterproductive to this site as a community, but playing tricks to hide the behavior, that I can only judge as ill-intend.
