AWL Troubles

[Clay Davis]

I need a quickie on the AWL.  It looks like some spam is getting assigned a 
negative score because of an AWL rule(?).  The messages are text and not too 
spammy otherwise, but from a layman's perspective, definitely not something 
that should be on a whitelist.  I know how to remove from the whitelist, but 
how did they get there in the first place?
 
Thanks, gang.
