It's not so much that we want to encourage upvoting specifically; voting on the substance of a node is always fine. Downvoting all of a user's nodes with prejudice is different.

Don't worry about triggering an automated detector; there is no such thing. Every now and then, or upon request, we can run a query which finds recent voting patterns. That's all.

Also, we would not take any action without first discussing it with the monk.
