As phpBB 3.0.6 contains many new spam prevention features, a new spam prevention topic has been created here
. Please direct all discussion regarding spam prevent in phpBB 3.0.6 to that topic.
I am going to close this topic as only the latest phpBB release (at the time of this writing is phpBB 3.0.6) is supported. At this time, any spam prevention posts will be met with a suggestion to upgrade to phpBB 3.0.6.
This topic will be preserved for the sake of archiving.
