I would like to make a suggestion.
Sooner than feel backed into a position where your only option is to give in to blackmail by the person who is unarguably the single greatest hindrance to the continued growth and prosperity of this site and community, I would suggest that you turn to the community, without which this site would be nothing.
Publicly announce the situation;
"People, this Arcturus guy won't stop hacking us. The first of these recent lockdowns was because he stole Dragoneer's account and used it to harass and ban a user. He says if we don't let him back in and allow him to be unofficial staffmember, he's going to keep doing what he's been doing anyway. We're at a loss of what to do. Do you guys want to keep going on as we have, and just bear with us through the occaisional downtime as we keep showing you our devotion and respect by trying our damndest to keep this guy out, or would you rather we let him back in, and trust that he uses the umpteenth chance given him to actually help this time?"
Or, inform the community of a third option.
"We presently have no good solution to Arcturus' hackings. We might look into hiring a professional full-time coder, not from within the fandom but from an actual business-like arrangement, to patch up the code and prevent further attacks from Arcturus, but this would be expensive and rely almost solely on support from you, the community. So what'll it be? Continue on as we have been, let Arc back in despite everything he's done to disrespect each and every one of us, or you guys help us pay for a professional to step up our defenses against him?"
There is ALWAYS another option. It's just a matter of whether or not you ask people for it BEFORE choosing from the choices you see and don't want to choose from.
