I'm idling in the top 10 channels, it's semi-active in that people pop in and say stuff, but there's no interaction. Most connections are from old bots, or from community pages that haven't been updated.
Yeah, I lurk in a community that _also_ has a Libera channel now, but they keep a bridge-bot in the old Freenode channel because all their old videos implore people to join them on Freenode.
It gets a bit of traffic, meaning those folks might otherwise be lost without the bot, so I understand it. It just sucks.
