Hello, I am currently working on developing a security and risk assessment service called Trust+, and I intend to release an add-on for Xenforo which utilizes the service. Trust+ will be launched with the following features; The ability to intelligently detect and block disposable email address domains. The ability to intelligently detect and block users using a proxy service. The ability to block users consistently identified by other Trust+ users as spammers, trolls, or spammers. The ability to use client-assisted verification to stop ban evasion, duplicate registrations, or other abuse. The ability for users to report DEA providers, proxies, or abusive users to the Trust+ service. The idea of this service is to prevent abusive users from reaching your community without having to manually approve registrations or annoy them by using CAPTCHA. Our API will provide a pass/fail value as well as a risk score, allowing communities the flexibility to choose the level of security they wish to employ. I am accepting suggestions and comments currently, and will eventually be accepting beta testers for the service. If you are interested in testing or have a suggestion for the service, please post below.
