[SC-Help] Stock inflaters?

[Keith Jillings]

Until recently, Spamcop has done a brilliant job.   As I posted above 
(and got no reply) stuff is now getting past the filters.  On watching 
the batches that arrive daily, it seems almost all to be these pesky 
"This stock is about to explode" scans.

They comes mostly from countries that are in my country blacklist - yet 
they get past the filter.   How is that?   Has Spamcop got a problem?
