Reporting & Statistics

You will get 2 reports letting you know how many spamming attempts were blocked in total and by type.

  1. The first report shows you the figures since you first installed the package
  2. The second report shows you figures for the last 31 days.

Here's a screenshot showing you the kind of results I got on my own website kalmoya.com:

3505 SPAM attempts were blocked from December 2, 2020, to August 18, 2021. That's more than 400 per month.

Where will spam blocking work?

Anti-Spammer Master will work with:

  • The core Express Form block
  • The core Legacy Form block
  • The core Conversations block
  • Private messages
  • Any third party form system implementing concrete5 Spam system

No anti-spam system is 100% foolproof. Anti-Spammer Master will do an excellent job blocking most automated spam and even some manual spam but your mileage will definitely vary.
