It seems like some folks will open up a profile and start voting up (and down) multiple posts from a single user within a fairly short time window. I beleive that this ends up getting flagged as "irregular" and the votes dissapear.
Can we introduce a limit of 8 votes a day for a single user's posts? In other words, I couild not open up Mr. Skeet's profile and vote on more than 8 of his posts within 24 hours.
I don't know what the limit would be for the "irregularity" pattern that gets identified in the batch proccesses, but that number could be good as well.
If you were to be coding an application, you wouod code to prevent the exception rather than swallow it and deal with the effects later, should this be any different?
