We've had our first (known) report of spam coming in from Matrix via the Incoming Webhooks. The message has been deleted here but we can't ban the spammer because they're active on Matrix, not Slack. Only a few channels have incoming messages from Matrix: #community-matrix #cljsjs #macchiato #rum and #cljs-experience -- are folks still finding those inbound bridges useful? Are the connected Matrix channels still active? We'd like to disconnect some of these to reduce the surface area for spammers so we need to know if we're going to break anyone's flow by doing so...

...I just took a look in all of those channels and some of them seem pretty dead and none of them have had any incoming posts from Matrix for years at this point. Maybe a case of "Going once... Going twice..."
