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 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 😄
This is most likely my favorite add-on developer. Signup Abuse and Protection, User Essentials, and Conversation Essentials are all must haves for your forum site. Furthermore the dedication and hard work Xon has shown in keeping his add-ons up to date and bug free are tremendous. All three add-ons are well worth the price.
Xon has some of the most useful addons and this is one of them. He also has unrivaled support. Literally fixing bugs within a day.
I was looking for an alter ego detector and this is the best, i love the multi-account to thread without making duplicated threads. Xon support is a plus, worth every penny.
I was looking for that add-on since a long time, and now he is available! Xon is fixing every report bug very fast, thank you!
Absolute essential add-on to reduce tedious moderator work and cleanup. Extensive set of options let you tweak rejection logic to suit your site making this add-on a no-brainer. Have been using for a few weeks now and can't imagine going without it for future projects.
Xon's take on this addon has been a blessing for our site. It helps track Alts, stop VPN abuse and so, so much more. We had a problematic user who after a long tale involving months and 80+ alternate accounts and several VPNs, finally got put in their place and prevented from returning to the site with this addon. Every attempt for this malicious individual to return has been stopped in its tracks since then. I won't also forget the rest of the more normal ban evaders and the such.

Buy this, you won't regret it.
