From (simple) multiple accounts detection to isp/connection fingerprinting with score-based moderating/rejecting logic. These are very effective low-hanging fruit at reducing spam.

Supports migration configuration from the following XF1 add-ons;
  • TPU Spam Detect
  • Alter ego Detector
See the FAQ Known Issues for known limitations. This is not a turn-key solution, and each site may require customization!

For multiple account detection, supports reporting to reports/threads. And will send reports to the same report/thread. To send to thread you must select the "Multi-account to thread" extra.

For connection fingerprinting more additional information is collected and recorded on the account.

Note; Configuration defaults are conservative, aimed at blocking VPNs and proxies. There are a large number of configuration options for this add-on!

Link content spam checking

Instead of adding the spam phrases http:///https:// which generate lots of false positives; this allows controlling how links are treated by the content spam checker;
  • Explicitly allow URLs with a given domain
  • Explicitly moderate URLs with a given domain
  • Explicitly reject URLs with a given domain
  • Default allow/moderate/reject for unclassified URLs

Multiple account handling permissions
  • Bypass multiple account checking
  • Can enable / disable alerting for user
  • Can enable / disable alerting for log
  • View reportings.
Use Multiple account to thread add-on to send multiple account reports to threads.

If you have a large forum and are not using this, you are screwing yourself. This addon is insanely good and the developer frequently updates, unlike most addon devs...
I've used this for over a year on a large forum with over 20 million posts. It's been working with no problems. We get a LOT of spam signups and this is pretty helpful to get rid of them. Configuration is complicated, and it does reject some users who I later choose to accept, but it works.
So glad to see this addon with updates as needed! The work you put into this is very much appreciated!
The most useful XenForo add-on. Combats duplicate accounts, bots, spam, VPNs, proxies, bad IPs. Worth every cent.
Another addon truly worthy of a 6 star rating.

Hugely powerful with a plethora of options, and constant evolution to ensure that any new potential ways to allow spammers/scammers into your site, is slammed fast.

The ASN Connection matching and proxy blocking is absolutely brilliant and when configured correctly you end up with an insanely powerful protection mechanism for your forum.

If you value your forum, buy it. It really is a no brainer!
Absolutely essential tool for preventing targeted spam from VPN users, mechanical turk farms, etc. 2.x has been missing this and Xon delivered. Importing our old settings from TPU Detect Spam saved a lot of time.
If configured correctly, completely stops spam and banned users from coming back and trying to cause havoc. With the GetIPIntel integration added in 1.6.0, it does a great job at detecting proxies/vpns and "bad ips".
An absolutely essential addon for preventing spam. I couldn't have upgraded to Xenforo 2 without it. Great flexibility for deciding who should be automatically moderated or rejected. By tweaking the number of points for certain countries, javascript disabled, email extensions, etc, it's possible to prevent the vast majority of spammer from registering and posting.
A very sophisticated add-on which brings a huge number of configurations-options with it. Fight spammers successfully with this add-on. Every cent worth it and another must-have!
This add-on has greatly reduced the amount of spam we get over @ our site. Prior to installing this, multiple spam accounts per week would slip through and be allowed to post spam threads. 99% of them are caught by the advanced filtering rules in this mod.

Highly recommended for any website suffering from a spam problem 😄
