Spam and bots shouldn't affect your gameplay at all, just password your games silly.
Yeah, totally! Spam and bots don't affect your gameplay at all - just play passworded games!
Are you freaking kidding me? You're saying rampant spambot harassment is OK because we can just give up public multiplayer games and play alone in a passworded one? How is this any different from TCP/IP or Single player? Stupidest thing I've ever read, congratulations.
