Somebody starts a site for collecting "scholar dropouts"? An article qualifies as a scholar dropout if:

- it was previously available on Google Scholar

- it cannot be retrieved, or the search on Google Scholar gives a misleading result (for example it gives another article, as explained in [1])

Please help to make a list of scholar dropouts! Thank you.
