In the etc/matterbridge.toml configuration for the wm-bridgebot libera.chat irc account at the global level we have:

# Ignore some spammy irc bots
# wm-bot: ##wmhack, #wikipedia-bn
# AsimovBot: #wikipedia-bn
# FIXME: can we do this per channel/bridge with tengo?
IgnoreNicks="AsimovBot wm-bot"

After asking for ideas on how to control this per gateway (the connection of 2 or more bridges to each other) in the #matterbridge libra.chat channel, I was pointed to the [gateway.inout.options] (0) configuration section which in theory will allow this to be set.

• Verify that this config parses and works with a controlled experiment
• Move blocks down to the gateway level if tests are successful
