My suggestion is that whenever the bot is offline then the clock starts ticking, and when that clock passes 24 hours every vip/sponsor gets 2 day added to their subscription. Remember that this does not count if JaGeX did a Client directed bot bust because that would mean OsBot would lose a significant amount of money, we don't want that. This would give incentive to both parties, and this is why;
Customers: You have NO need to rage anymore if this happens, you will be getting 2 extra days added to your account every 24 hours that the client is offline, so why would you complain?
Developers: This will give you the incentive to update as fast as possible, this could be a fun thing for you to race against the clock, but it could also be a bad thing for you guys if it does pass 24 hours.
An automatic system CAN be put into place for this as well.
Every 24 hours after the bot has been down then you will get 2 day added to your subscription
