marceloneil [1] filed a deletion request for electrum [2]:

This AUR package was created when the electrum package was removed from the community repository last night. It has since been readded, and so the AUR package is unnecessary and no longer follows the Rules of Submission (https://wiki.archlinux.org/index.php/Arch_User_Repository#Rules_of_submissio...)
