@soc@snarfed.org@snarfed.org I recommend then either blocking the bridge or selecting one of the options they provide to opt-out. Their # nobridge tag is thorough because it'll also opt you out of other bridges running their software, but if you don't like that you can just block their bridge's instance.
Be aware though that if you're on the fediverse and not on a whitelist instance, you will be bridged to all reasonably compatible federated networks.
