These are non-issues, broadly. The hypothetical restaurant that had bad press / reviews / etc. long ago will be critically evaluated by the public, who are not incapable of coming to the conclusion you suggest, that 10 years of no (or good) news outweighs the old blot on their record. If employers of the future use data mining to expose every trivial misstep of candidates for hire and then turn away all those who aren't perfect, they won't have any employees. In fact, it reminds more than a little of the difference between having a credit history, however bad, vs. having no credit history at all - typically lenders are much more wary of no history, rather than a bad one (within reason).
