> Retracted? Yes, but only after an investigation, the results of which would then be made public by way of explanation.
Just to clarify: when papers are retracted, they are not normally erased from the database and replaced with an explanation. See this Nature paper for an example; the entire paper is kept available online, just as before, except that the words "RETRACTED" is stamped on each PDF page
Likewise, nothing published to the arXiv is ever removed. A retraction notice can be added as an update, but the complete version history is always available.
Articles are much more likely to be "un-published" (wiped from the archives) in journalism than scientific publications.
