When paste creation rate exceeds threshold, PoW difficulty increases to slow down attackers. Decays back to base when abuse stops. Config: - ANTIFLOOD_THRESHOLD: requests/window before increase (30) - ANTIFLOOD_STEP: difficulty bits per step (2) - ANTIFLOOD_MAX: maximum difficulty cap (28) - ANTIFLOOD_DECAY: seconds before reducing (30)
