Steven, perhaps you can explain why upvotes are valued differently from downvotes?
In as much as you can credit an upvote, in direct numerical relation to how many you have received,
- from the very first - yet if you have a standing total ( & regardless of how many you have actually received),
of fewer than ~25, (is it?) you have zero downvote capability..
& why cant you apply downvotes in numerical equivalence - to those you have received - too?
Logically, this debases the value of the system... & at the very least, allows a potential injustice situation..
As to the O.P. 's concerns, I'd suggest that if you consider the 'offending' post meets the criteria of being
off topic/trollish, you ought to report it.. some posts do seem to vanish, & most likely, from this effect..
