Thank you for this feature! I'm really happy to see both sides: ignore and follow. This will make for some interesting data mining. For example, maybe I could trust ignores made by another account (they might be exceptional at flagging disinformation for example).

It was a bit confusing to see the follower account twice so I looked into it. It looks like required_posting_auths is used to track the bandwidth (does this account have enough bandwidth to post this operation) and is not necessarily the follower. I see in the plugin, the follower must sign the operation, so obviously we don't want other people telling us who to follow. These will probably always be the same so one signature is required.

For the operation to be valid, it looks like we need an empty array for required_auths...
