The statement coming from someone who was on a topic creating spree yesterday... Ironical, isn't it?
First check on your posting habits before you start moaning about "Signature spammers'. Imagine if each one of us had to open a topic every 8 minutes

A spam free forum starts with you.

Lmao this is just one of those white knight topics in the hopes of gaining merits. Hurr durr people spam Bitcointalk.
OP, mate, there's definitely A LOT less spam right now than how it was back in the day when there was no merit system. I'd say Bitcointalk is in a really really great situation right now as conversations have been a lot better(at least in my opinion). Spam posts have been a lot easier to differentiate from actual constructive posts due to the lesser spam posts because of the merit system.
