Is there any concrete evidence I can get in a report related to my spam submissions that any of what I have sent has made any difference? Is it worth my time to continue to send them, or is it a losing battle and I should just stop and either live with spam filters or get a new email address and start over?
It all depends on what you mean by '...made any difference...'
If you mean, in effect, that you don't see any less spam arriving in your mailbox then the answer is likely to be: No it won't make much difference unless you or your ISP make use of the SpamCopBL.
But, as Miss Betsy says, your reports do contribute to the block list and that does, in turn help those who do make us of the SCBL.
Does it make any difference in terms of ISPs cutting off spammers? Only when responsible ISPs are involved but as so much spam is now distributed either by Spammers own machines and, increasingly, through computers compromised by a trojan, the impact is only short lived since as soon as one breach is plugged another is discovered.
Certainly my own ISP is very proactive and respond very quickly to SpamCop reports.
So thatnks for reporting... Please continue if you have the time.
