1) Crew people don't gain reputation or rank
2) Money is absolutely meaningless and if someone wants to AFK to make some money while someone else is shooting spacemans I mean who cares really? Surely that's their problem as they are the ones missing out on playing the game.*
3) A single extra pip, even two extra pips, is such a small intangible benefit as to not really matter at all, now, isn't it? I mean,
(a) who really cares if somebody has two extra pips
(b) if I am that concerned about it surely I can just have some of my friends provide me some extra pips too
(c) if it doesn't directly effect anyone but the players involved I fail to see how it's a problem at all (see 3a)
*If you are concerned that someone is getting money while not playing the game, the concern really has to be in terms of them missing out on playing the game. If we instead say "they should have to play the game, be forced to play the game" then the problem isn't that they are getting money, but that the game is one where people literally need to be coerced into wanting to play it. I would rather a hundred thousand people AFK multicrew grind money and one person actually shoot spaceships and have fun, than a single person feel the need to scum for missions or do Robigo or whatever else because the game isn't fun on its own.
