It's really not that bad. You can turn off signatures in your settings. And if there were no idiots, no one would have time to talk on the forum.
It's not the signatures themselves, it's the mindless drivel that is posted because of a post-count driven system. I'm aware of DannyHamilton's list and it's great, but god damn this forum has gone to shit.
You are so cynical, without bitcoin signature campaign, bitcoin can't be so huge like today, signature campaigns help bitcoin websites, bitcoin related companies and the forum itself, you are obviously a naive boy, thinking without brain.
