It's just another station cheat in the long line of station cheats, stop it and they'll just switch to something else exactly as they always have.
While I respect your opinion it's a grey area I disagree, and I'll still block anyone who does it.
Oh, in my opinion it is not a grey area either - it is clearly not an exploit. But that is why it actually is a grey area, because we both have differing opinions, and there are reasonable arguments on both sides (I think).
Personally, if I was prevented from landing on a pad I'd have no qualms about logging out and going into another mode. That kind of behaviour simply wouldn't be tolerated inside a space station (imo), but the game isn't yet smart enough to do anything about it.
