BellaBuzz v2 on my site has been subjected to occassional spams so I came up with this simple counter-spam technique. I cannot guarantee it will work for you but so far it has served me well.
Since BellaBuzz v2 comes with the checkbox that serves as spam control. It is unticked by default so what you have to do is change the setting so that it will be ticked by default. Therefore,in order for someone to be able to submit the question, the user will have to untick the box first.
So, how do you do this? It’s pretty simple.
Open up the functions.php file and look for this line:
<span style="display: none;"><input type="checkbox" name="human" id="human"> <label for="human">Leave this unticked if you're human :)</label></span><br>
Do the following:
1. Change the display: none to display: visible
2. After the id=”human”, add value=”ON” checked
Save the file and you’re done.
