If you want high-quality posts, remove the signatures campaigns from the forum.
I disagree, "if you want high-quality posts" :
- remove the low-quality posts;
- remove the low-quality users;
- educate instead of complaining.
By the way, low-quality or high-quality post is highly subjective.
If we remove all the signatures then the ranks will become irrelevant because the newbie and hero members, both cannot have the
signatures.
