# Description: A blacklist script that stores the banned masks in a db file #

#         Thanks to strikelite and user (if I recall correctly) from the    #
#         egghelp.org forum for helping me with this script (back in 2003). #
#         Also used user's (egghelp.org forum) maskhost proc.               #
#                                                                           #
# History:                                                                  #
#         - 1.4: Fixed a bug when using the bansame option where nicknames  #
#           with special characters (\, [, ]) were not properly banned.     #
#         - 1.3: Added Flooding out protection, where the bot will start    #
#           using the slowest queue in case a number of blacklisted users   #
#           join in a certain period of seconds which can be defined by the #
#           user. + fixed a bug with brackets.                              #
#         - 1.2: Fixed a few bugs and made the script create the blacklist  #
#           file if it doesn't exist.                                       #
#         - 1.1: added the black list chan flag, and other features into    #
#           patterns of handling the blacklist.                             #
#         - 1.0: First release.                                             #
#                                                                           #

## Blacklist File:
set blackl(file) "scripts/blacklist.txt"

## Blacklist "Excess Flood" protection. Set here how many blacklisted users are allowed
## to join in how many seconds before using the slow queue in order for the bot not to
## flood out with reason "Excess Flood."
set blackl(punish) 4:2

## Do you want the bot to also check for blacklisted users on op ? (0: no / 1: yes)
set blackl(checkop) 1

## Do you want to ban the same ban from the blacklist file
## or do you want it to be spcific ? (0: specific / 1: same ban as the file)
### example:
## Suppose that *!lamest@* is banned.
# .. joins lamer!lamest@lamer.org
# .. bot sets mode +b *!lamest@*
# .. lamer kicked by bot "Blacklisted user."
## This happens if this option is set to 1.
## but if you set it to 0, then you can choose what bantype you want to ban.
set blackl(bansame) 0

## if blackl(bansame) is set to 0:
## What ban type do you want to ban ?
# 0: *!user@full.host.tld
# 1: *!*user@full.host.tld
# 2: *!*@full.host.tld
# 3: *!*user@*.host.tld
# 4: *!*@*.host.tld
# 5: nick!user@full.host.tld
# 6: nick!*user@full.host.tld
# 7: nick!*@full.host.tld
# 8: nick!*user@*.host.tld
# 9: nick!*@*.host.tld
set blackl(btype) 2

## Set default ban reason if not specified.
## NOTE: use %requester to use the nick of the one who set the ban.
set blackl(kmsg) "Banned: Auto-Ban"

## set default ban time (in minutes) if no bantime specified. (0 means no ban time)
set blackl(btime) 0

## Do you want the ban to be removed from the file after ban time expires ? (0: no / 1: yes)
## if set to 0, the bot will only remove the ban from the channel but not from the file.
set blackl(rbabt) 0

## Set here the trigger for public commands.
## example: set blackl(trig) "!"
## now using !listbl on main will show the blacklist.
set blackl(trig) "!"

## Set flags that are allowed to use these commands.
## <global flags>|<channel flags>
set blackl(flags) A
