On the Japanese Wikipedia, we experienced a series of serious vandalism that indiscriminately changed edit tags on existing revisions (e.g. [[ https://ja.wikipedia.org/w/index.php?title=%E7%89%B9%E5%88%A5:%E3%83%AD%E3%82%B0&type=tag&user=%E3%83%A6%E3%83%BC%E3%83%A2%E3%82%A2%E6%AC%A0%E8%90%BD%E8%B3%9E&uselang=en | 1 ]], [[ https://ja.wikipedia.org/w/index.php?title=%E7%89%B9%E5%88%A5:%E3%83%AD%E3%82%B0&type=tag&user=Efiugjb&uselang=en | 2 ]]). Given this, [[ https://ja.wikipedia.org/wiki/%E7%89%B9%E5%88%A5:%E3%83%AD%E3%82%B0?type=managetags&user=&page=&wpdate=&tagfilter=&wpfilters%5B%5D=newusers&wpFormIdentifier=logeventslist&offset=20230731122511&limit=8&uselang=en | manually added edit tags have all been disabled ]], and we had a [[ https://ja.wikipedia.org/wiki/Wikipedia%E2%80%90%E3%83%8E%E3%83%BC%E3%83%88:%E3%82%BF%E3%82%B0#%E3%82%BF%E3%82%B0%E7%B7%A8%E9%9B%86%E6%A8%A9%E9%99%90%E3%81%AE%E5%A4%89%E6%9B%B4%E6%A1%88&uselang=en | discussion ]] for a countermeasure to re-enable the tags.
