When I first launched BioStor (an article finding tool built on the top of the (Biodiversity heritage Library) I wanted people to be able to edit metadata and add references, but also minimise the chances that junk would get added. As a quick and dirty deterrent I used reCAPTCHA, so anybody adding a reference or editing the metadata had to pass a CAPTHCA before their edits were accepted.
