Limiting the payout should reduce votes, given that people voting it higher than $25 are not only wasting their vote but also earning zero curation. It may not happen immediately as there are some programmed votes and people may make mistakes, but few like to continue pissing money away, especially larger stakeholders.

The first capped post got voted up to $53 ($28 worth of wasted voted), but the second up to $33, and the third up to $31. So it does appear people are figuring it out.
