[Issue] No method exists to ban Matrix users harassing the bridged IRC<->Matrix channels

[jahway603]

I have looked thru the documentation and unable to find any current methods that exist to ban Matrix users harassing the bridged IRC<->Matrix channels that are maintained by Matrix.org listed here https://matrix-org.github.io/matrix-appservice-irc/latest/bridged_networks

Is this on OFTC? Ban them by their unique IPv6 address.

Yes, it is on OFTC.

The issue is not really clear. After talking in the chat the actual issue are bans and K-Lines not getting bridged to Matrix under certains circumstances. As a result some OFTC channels have lots of spam on their Matrix portals, but the IRC side doesn't get any of the spam.

[Half-Shot]

True K-Lines should be actioned as users should be kicked from any room they are unable to get a IRC connection in, unless the room admin has opted to de-op the bridge and is unable to perform the kicks (which is in itself a problem). Are there example rooms we can take a look at?

[mweinelt]

X-Lines should be considered as well. We are currently observing appservice-irc catching up for hours due to a wave of account spam joining over the bridge. The bridge is now trying to reconnect all these users after a restart and takes hours to iterate over all these hosts.
