I totally agree if the downvotes are as of result of unnecessary upvotes or if they're over voted..or from spams ...or suspicious activities...
When it's personal it makes downvotes look like the perfect weapon for warfare..
There's still no real definition as to a post can be valued..you might find value in a post and someone else might not, still doesn't make it undervalued or overvalued.. relationship also play a significant role..so I feel the issue of vote distribution will still be a major problem here on Hive
