If one (accidentally) adds one or more new references to a OA journal/publisher, basically pay-to-publish publishers, one gets the warning below after clicking "Publish changes":
Warning: An automated filter has identified this edit as introducing references to a predatory open access journal or publisher. Predatory open access publishing is considered self-publishing due to lack of peer-review and predatory journals are rarely, if ever, appropriate for inclusion in Wikipedia. If you are confident that you want to cite this source anyway, please click 'Publish changes' again. Note that citations to predatory journals are routinely removed.
The problem is that it includes a long list of DOIs of such publishers but doesn't tell you which were detected (see screenshot below).
This means you have to do something like searching for all the many DOIs there one after another to find the one/s that were detected so that you can remove, check or replace them (which takes a lot of time if the user even puts up with that instead of aborting the edit). It should only display the DOIs that were detected or highlight the detected items of the list or list the detected ones separately to the list.
It has to detect the DOIs in some way so it should already be easily possible to display these DOIs.
