Devs could add a “Groundhog Day” emergency reset button to VIP PASS (“now with no regrets reset button. Protect your investment from fumble fingers today”).
Pressing it resets your account to 12:01 AM UTC the day before ( so 24- 48 hours ).
Example
At 5:00 PM UTC on Friday I hit the reset button, my account resets to 12:01 AM UTC on Thursday.
This would cost you
1-3 days of titan loot
0-1 days war loot
0-1 war chests
0-1 Class quest rewards
0-4 Wanted Monster mission chests
0-4 Wanted Hero mission chests
0-1 Rare Wanted Monster mission chests
0-1 Wanted Titan mission chests
any 4* / 5* heroes you summoned
24- 48 hours of training camps, farms, mines, both builders, Forges, etc.
Edit:
0-1 days of VIP Pass ( gems, loot tickets, emblem, etc.)
Edit:
They would just disable the feature for non VIP PASS accounts so you could make a mistake, purchase a 30 day VIP PASS and immediately use the reset button.
While I think misuse in war and upcoming Weekly Group Raids is, well, overblown, the reset button could automatically put you in SPECTATOR MODE for war.
