Hello. When AbuseFilter blocks an user that triggers a filter, the filter does not seem to allow talk page access so it's imposible for IP addresses blocked to even appeal this automatic block. The fact that blocked users are not allowed to use talk page access is not noted, either, in the block log but on the Special:BlockList page. Please compare:
- BlockLog: http://es.wikibooks.org/w/index.php?title=Especial%3ARegistro&type=block&user=&page=User%3A126.96.36.199+&year=&month=-1&tagfilter=
- IPBlockList entry: 00:28, 11 August 2011, Filtro antiabusos (Talk | contribs | block) blocked 188.8.131.52 (Talk) (expires on 12 August 2011 at 00:28, anon. only, account creation blocked, cannot edit own talk page) (Bloqueado automáticamente por el filtro antiabusos. Descripción del filtro que se ha disparado: Vandalismo corriente #1) (unblock | change block)
So in the block log appears that the IP is hardblocked (the "block anonymous users only" box unchecked) and that talk page access is allowed. Yet, on the BlockList the IP appears blocked with anonymous users only, account creation disabled and talk page blocked.
The filter should hardblock IPs but allow talk page access. The "angry-autoblock" for IPs makes no sense.
As for registered users: account creation blocked, autoblock and angry autoblock, but talk page access allowed.
Hope that its clear otherwise please ask. Maybe this can help http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/AbuseFilter/AbuseFilter.class.php?view=markup&pathrev=90285 [line 1011 & ss.]
