No - the +143 means "143 supplemental links were 
successfully downloaded in background processing, and are 
waiting for inspection". Therefore you can 
read '334+143/1457'

A general remark: when you have many bad external links, it 
might be better to use -* as first filter (exclude 
EVERYTHING), and then accept servers name by name.
