Actually, there is a feature in the forum where you cam disable it. So the tool would be useless...
Goto Profile- Look and Layout Preferences - Dont show users signatures
Goto Profile- Look and Layout Preferences - Dont show users signatures
I do want to see signatures. What I don't want to see is signature campaigns.
Then you need the signature campaign blocker (Blocks every user that is participating or willing to participate in a signature campaign)
And the difference between that and the software listed here is...?
