While a lot of my thoughts are intertwined in the post above, let me add a few things.
I did not participate in the vote, but the rest of the team was unanimously for the team member commission ban. There were varying degrees of strength-of-opinions but there was no one against this ruling.
Back at the start, osu! used to be a hugely creative game. Over half the community was here for the mapping/skinning side, not the farming/ranking PP side. This has obviously changed beyond return, but I hope that we can agree to uphold that mapping and modding is one of the many of the enjoyable aspects of the game and community.
I tend to let the community drive this game, which is why I am very hesitant to make calls like this, but due to the amount of heated internal (and external) discussion over this point I believe the above needs to be said to set some level of precedent. Hopefully you can understand.
