Hi folks, as some Matrix users already noticied some of our Matrix channels are targeted by big spam waves. As a temporary counter mesure, I made both #kde:kde.org and #chat:kde.org invite-only, but it's highly possible that the spam will move ot other channels since it seems that KDE is the target (some spam messages mentioned KDE and Plasma 4). If this happens to a room where you are the moderator, make your room invite only and ban every users who just joined (the username follow a pattern similar to this regex [a-z]*[0-9]{1,3}). Another solution is to setup ACL rules to ban the server to interact with the room[1]. But I'm not sure how efficient this is considering that the spam is coming from multiple small matrix server with open registration.
Probably a better long term solution would be to setup mjolnir[2] on our instance and that would allows us better manage spam and also share block lists with gnome.org and matrix.org homeservers for example.
