KDE now has its own Lemmy instance
(lemmy.kde.social)
KDE is an international technology team creating user-friendly free and open source software for desktop and portable computing. KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows.
By default, lemmy will federate openly with any other instance. You can then block specific instances. (Disallow-list)
You can additionally disable federation altogether, or only federate with a specified list. (Allow-list).
