I haven't seen this discussed here yet. Wikipedia has decided to deprecate archive.today links because the site has been observed using the browsers of visitors to conduct a DDOS attack on the blog of an individual. Perhaps more troubling, archive.today modified archived versions of articles to insert the individuals name into the context of the articles.
