Quick access to filters on spam invasion via prefixes for filter-names.

First you should define an alias like
  /alias /f /filter add SPAM\$1 irc. * \$1

78 79 80 81 82
Sometimes the filter above will not work, eg for ctcp requests, then a more aggressive filter can help:
  /alias /fa /filter add SPAMAGR\$1 * * \$1

  Note y'll never see lines with regex (\$1) again!

83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106
With this alias you can simply add filters for spam with copy and paste. 
  /f copy_and_pasted_string

With the alias /f, defined above, filters like

  [SPAMcopy_and_pasted_string] buffer: irc. / tags: * / regex: copy_and_pasted_string

will be created.

Now you can simply list/disable/enable or delete them at once like

  /filter_ext del SPAM

Keep in mind 'SPAM' is handled as a perl regex, so all filternames containing 'SPAM' will be deleted. If you want del filter-names beginning with 'SPAM' use

  /filter_ext del ^SPAM

instead. (for perl regular expressions, look at: perldoc perlre)

To be more quick define aliases like:
  /alias /fddel  /filter_ext del ^SPAM
  /alias /fl     /filter_ext list SPAM
  /alias /fd     /filter_ext disable SPAM
  /alias /fe     /filter_ext enable SPAM
107 108 109 110 111
for aggressive filters:
  /alias /faddel  /filter_ext del ^SPAMAGR
  /alias /fal     /filter_ext list SPAMAGR
  /alias /fad     /filter_ext disable SPAMAGR
  /alias /fae     /filter_ext enable SPAMAGR
