Honorable retractions, as a result of honest errors, happen all the time in science and, while unfortunate, are not a huge deal.

Much different are the retractions based on research fraud. retractionwatch provides a valuable service in tracking all types of retractions, and in warning the community about unethical or predatory journals.

I like your term "honourable retraction".

But if people and retraction watch don't differentiate between these and dishonourable ones, then it doesn't really help.

Retraction Watch provides information. They do an excellent job in following up on incidents and supplying the complete picture. It’s always clear from their reports whether an author was shady or simply made a mistake—and this is usually clear from the author’s behavior, as well.

Of course neither they nor anyone else can be held responsible for unjustified assumptions of the mob, except the members of the mob.
