Limiting signature past the 1000 page probably wouldn't help all that much. I think the solution would be to better moderate these mega threads. Whether that's through increased manpower, community helping out or being a little more restrictive on mega threads. The latter probably being the least ideal solution.
I didn't expect it to completely eliminate or limit spammers, but I did expect it to reduce what we have now. Since you know there's a lot going on behind closed doors, and I know we've discussed it before, I'm curious why the activity of mods on the G, discussion board has decreased.
I wonder if deleted posts should have an additional merit or activity penalty.
What happens to members who delete their post history on a monthly/yearly basis?
