+# "bantime.increment" allows to use database for searching of previously banned ip's to increase a 
+# default ban time using special formula, default it is banTime * 1, 2, 4, 8, 16, 32...
+#bantime.increment = true

+
+# "bantime.maxtime" is the max number of seconds using the ban time can reach (doesn't grow further)
+#bantime.maxtime = 
+
+# "bantime.factor" is a coefficient to calculate exponent growing of the formula or common multiplier,
+# default value of factor is 1 and with default value of formula, the ban time 
+# grows by 1, 2, 4, 8, 16 ...
+#bantime.factor = 1
+
+# "bantime.formula" used by default to calculate next value of ban time, default value below,
+# the same ban time growing will be reached by multipliers 1, 2, 4, 8, 16, 32...
+#bantime.formula = ban.Time * (1<<(ban.Count if ban.Count<20 else 20)) * banFactor
+#
+# more aggressive example of formula has the same values only for factor "2.0 / 2.885385" :
+#bantime.formula = ban.Time * math.exp(float(ban.Count+1)*banFactor)/math.exp(1*banFactor)
+
+# "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
+#bantime.multipliers = 1 2 4 8 16 32 64
+# following example can be used for small initial ban time (bantime=60) - it grows more aggressive at begin,
