No, people asked him to leave because he negligently took care of the account of a colleague, given his leadership role in the alliance the members present at the meeting, to which everyone was invited, found this unacceptable and voted to remove him from the alliance. In any event the ban will almost certainly be temporary, and Mach had commendably come forward and apologized and many members of the alliance, including Ev0, have accepted his apology -- both sides have come together to try rectify the situation.
I can assure you that an alliance discipline policy will be a topic for discussion at the next meething, and I imagine that a re-invitation to MachOne may be under discussion as well, should a member wish to raise it. You'll also notice that MachOne still has access to our chatroom and the alliance forum.
If you or anyone else has questions about this feel free to direct them to me, post in this forum, or the other forum via the link I provided above. I'll do my best to answer them to your satisfaction.
You might also try to contact Boombexus, Cardude2004, or MachOne - but I cannot speak on behalf of those members here with regards to whether they wish to respond further to this situation.
Thanks.
