It's as though the comment is trying to prevent overracting, however weigh it against the threat of underreacting. The harm in taking these allegations too seriously (false positive) is doing research and finding out the statistics are invalid (extra research time). The harm in taking these allegations not-seriously-enough (false negative) is mass-scale election fraud.
Given how hard it is for such allegations to even be considered at all in our social climate (even when we all know they're much more technically feasible than people would like to admit) I think a defusing this article detracts from pursuit of truth in exchange for peace of mind.
