Deleting individual posts in isolation does nothing. A sig spammer is always incentivized to make more, and can churn them out just as fast as we can report them. If you start doing something which will actually affect their income - temp bans - then they may be motivated to change. If after multiple temp bans they are still not motivated to change, then a permanent ban provides no loss to the forum.
That sounds good to me.
The problem is the rules need something between a slight adjustment and a complete overhaul. A lot of posts are empty calorie garbage but don't technically break any rules, thus they're not likely to be deleted and I'm not likely to report them.
