As posted in https://progress.opensuse.org/issues/166865#note-2: Synapse supports banning servers on a per-room basis via room ACLs, See "Banning servers from rooms (Server ACLs)" in https://matrix.org/docs/older/moderation/. This cannot be done via the Element UI, but the page documents how this can be done via development tools. This could be an option to block certain unwanted servers, even if they are big ones.

Hi everyone,

due to an influx of abuse we reduced the Matrix federation with the servers behind matrix.org for the time being. Due to the design of Matrix it seems to be not possible to completely inhibit it, hence you will notice "broken" behavior when trying to join openSUSE Matrix rooms from a matrix.org account, or an account on other Matrix instances using their hosted service.

We encourage you to instead use an opensuse.org account via https://chat.opensuse.org/ or to join us on IRC.

This effort was tracked via https://progress.opensuse.org/issues/166865, where more details are to be found.

We are furthermore discussing ways for better abuse mitigation.

Thanks, Georg
