Although I know there is this discussion regarding increasing the down-vote weight, I am currently often getting reports of serial down-votes from various high reputation (20K+) users on Super User complaining about the loss of reputation. Although the latter is a problem, it is not extremely easy for the mods to track these without the help of the development team directly.
As much as I recognize that serial down-voting is a problem and is being handled to some degree, when you have 10K and more seriously have in the upper 15K+ range of reputation, does the few times a month you receive a down-vote really become such a problem compared to the rate you are gaining reputation?
Should you even be bothered at such high numbers? Or should you just shrug it off?
