My forum started to get a lot of spams since the beginning of this month. The spams were from some kind of spam bots. My first reaction was to find SMF mods that can deter the spams from coming. There are a few mods available for fighting spams. However, I could not get these mods to install for some reasons.
Finally, I came up with a way to stop the spams without additional mods. Here is what I did.
- Click on ADMIN menu and click on Registration on the left.
- Click on SETTINGS.
- Change Complexity of visual verification image: to High: Angled letters, considerable noise.
After the changes, there are no more fake users created by spam bots.
