services.fail2ban.bantime-increment.multipliers

"bantime.multipliers" used to calculate next value of ban time instead of formula, corresponding previously ban count and given "bantime.factor" (for multipliers default is 1); following example grows ban time by 1, 2, 4, 8, 16 ... and if last ban count greater as multipliers count, always used last multiplier (64 in example), for factor '1' and original ban time 600 - 10.6 hours.
