Check Proxy RBL on New User Registration Version 4.1

Version 4.1 includes remains unchanged from version 4.0 with the exception of a code fix to deal with an SQL injection security hole in the code.

What does this hack do?

Hooking in at register_addmember_process and register_addmember_complete this hack compares the IP address of the person registering with the Realtime Block List(s) of your choice. Based on your configuration the RBL Checker will then perform one of these actions:
  1. Nothing, the registration continues as normal.
  2. Registration continues as normal, but the user is automatically moved into the "Pending Moderation" group of your choice.
  3. Registration continues as normal, but the user is automatically permanently banned.
  4. Registration is blocked, an error message is displayed to the user.
Please Note: It is strongly recommended that you configure PM or Thread based notification so that you may monitor registrations that are from IPs that are a positive hit on the RBL. Especially if you configure the checker to allow registrations to complete normally.

These options are configurable in AdminCP > Options > DM-RBL Check on Registration.

Why Block Proxies?

Banned and Spammers users often get around IP bans by simply using an open proxy - of which there are thousands - to get around the IP ban. Very few legitimate users slow their surfing by using an anonymous proxy.

How do you Install?
  1. Create a user from which PMs, Posts, etc. will be generated.
  2. In your adminCP obtain values for the "banned" and "pending moderation" groupIDs (Defaults are 8 and 4).
  3. Install the attached product.
IMPORTANT NOTE:You must specify a username if you plan on configuring the AUTOBAN or NOTIFICATION options. Otherwise you WILL get errors.

What is the default config?
By default the RBLChecker will check the IP of a new registration, allow registration to complete, but add the new user to the "COPPA Members Awaiting Moderation" usergroup. You can then approve/reject those members depending on whether you think they are/aren't spammers/trolls.

You can modify the settings in the AdminCP to Ban or Block as you like.

I have installed this on 3.8.4 it didn't break anything so far so I guess we will see how it goes as far as being effective.

I'm trying to update this plugin with TMM-TT's advise. All of a sudden I'm getting bombarded with auto registrations. They post a DivX url and add all kinds of garbage into the profile "Man, ICQ number......". So annoying.

I know this is a strange questions, but has anyone tried this on 4.2? I don't see any good RBL registration blockers for the 4.x series.

Just looking to clear up the database a bit and was wondering if i temp[orary uninstall this mod, does it remove any database tables with it.

If so, what are the specific tables/columns created by this mod?
