Use
https://www.warzone.com/Forum/299366-hide-threads-replies-poster-official-3 instead. There isn’t a way to automatically import the data on “wally”’s. What you can do is install the latest version of my hide threads and replies script, click on Dan’s Userscript, click on Add Players, click on Username and then type/copy and paste a player name. If you encounter an error, click “Yes” to allow an error report to be sent. Doing this allows me to quickly resolve the bug.
May I ask you why you’re using “wally”’s version? Mine is maintained while I doubt Wally understands how “his” works yet alone maintain it.
