Problematic word associations
Some of the features on OneLook, such as the OneLook Thesaurus
and reverse dictionary, are enabled by a statistical analysis
of the words in a large collection of books written in the past
century. A handful of times we've found that this analysis can lead
the system to suggest word associations that reflect racist or harmful
stereotypes present in the source material, and we remove them. If you
see one of these, please know that we do not endorse the association
itself, and we'll seek to remove it from the site if you report it to
us via the feedback box below.

the operator of OneLook.
The server keeps a log of the queries made to the service in the last

than a count of the number of requests.
