This is a tricky one for sure. Can see both sides of the argument.
For polls, if I'm the pollster, I'd much prefer being able to set a "vote minimum" and "vote maximum" where any vote less doesn't count, and voting over the max still results in 1 vote. The range could be chosen by the pollster allowing it to be tailored to the situation (seriousness, likelyhood of being brigaded, topic, etc)
But for a typical post, I think it really depends on how we want to view that stat. Is it an improved "like" showing you got my attention, or is it a tip jar showing how much I valued the content? I kinda feel like it should be seen as a tip jar. Healthier incentives
