I intend to put out an updated September list within the next day or two.
Note that even with my list you will still see some posts with signature campaigns. As the month progresses, there will be users that join campaigns and you won't get them on the updated list until the end of the month.
Additionally...
if I happen to see that some other user quotes something an ignored user says AND the quote indicates that the ignored user is creating thoughtful and useful posts, I click "unignore".
Meaning that my list does not "ignore" users that have consistently proven themselves to be able to avoid the temptation to spam the forum with nonsense.
Some examples of signature campaign participants that I do not currently ignore are:
jonald_fyookball
LaudaM
Quickseller
You may feel differently about some of these users than I do, and as such you may want to maintain your own list (or at least keep track of which names you want to add to, or remove from, my list).
