In another topic this discussion came up for a updated spider/agent list.

Currently there is not a way for us users to update a list on this site.
And the stock code has not changed for quite some time.

But it would be a nice to have or at least the moderators have a current updated list posted.
I know it is a revolving door keeping up with them but....
My list as of today is:
