The most reliable method for detecting list scraping is using tagged 
addresses. Of course, some spammers are smart enough to remove plussing, 
although some systems are designed to require the plussing to get around 
this.

In general, the total spam sent is on the rise. Dictionary attacks are 
on the rise (and no offense, but your username would probably be in 
every dictionary attack list, as mine is in a lot of them).

There are reports done up and usually published showing the most used 
methods of spam addressing methods (scraping lists,Usenet,web,whois; 
dictionary; greeting cards; trusted companies selling the address; etc). 
I recommend you check google or ask around on Spam-L where many admins 
can do a quick database search and pull the counts for different types 
of tagged addresses.
