I am a member of another forum that uses SMF software, and it has been inundated by spam threads (offering a variety of drugs, etc) recently. Almost all of them end with the comment
Sorry for choosing "area title" to leave a offer for you about ...
Does the SMF software have a facility that allows trigger phrases to automatically delete such threads/posts? Note that the spam doesn't appear in the middle of existing threads, but only in their own threads. Do we suffer from this or are we too small to attract such stuff?
Are you talking about the new Religion and Ethics forum, which is having the problem you describe, it is a real pain?
