I had a fine in Aditi and thought I'd probably actually pay this one because I couldn't be bothered with constant interdictions now that I'll be hopping to less capable ships, not that there's a ship in the game that can't outrun 99% of interdictions with submit > boost, it's just an annoyance if you're not going to blow them up.
Anyway before doing so I went to a CZ to get some Hybrid Capacitors, then on to a platform to collect the bonds from the CZ. While There I saw an Interstellar Factors Contact, I had no idea there was now a service to pay fines remotely, they charge a bit, 25% commission, but for me it was worth it. They also collect on bounties, I had 4mil+ all over the place, I was never likely to collect them so was happy to collect them even with the charge.
Would prefer 20% and I did get stuck in the menu and didn't seem to be able to exit without quitting

but still, another nice QoL addition in 2.2.
