Didn't some Mobius players orchestrate some attack on some PvP groups system through the BGS and only staying in Mobius? Sounds comparably immature as to what the SDC does.
And remember when the forums cried about the ruins puzzle only being possible to do in open which wasn't even true?
It wasn't just Mobius players, and it was players in all modes, so to answer your question, no.
As for the ruins puzzle, what does that have to do with members of Mobius Group maturity level?
