Spam-O-Matic for VB

attroll · 2022-02-13 3:13 am

I am a little confused. Let me explain.
I have a user that is getting the following message when they try to register on my forum.
“Registration denied, this forum runs and active policy not allowing spammers. Please contact us via the “Contact Us” page link if you believe this is in error.

They do not seem to be a spammer, yet there being blocked by the GlowHost addon.
There IP is 2600:387:a:5::17. If I go to the stopforumspam web site and do a search for that IP and check box the EXACT MATCH, and I get the 190 results for 2600:387:a:5::/64. If I click on EXACT MATCH, why is 2600:387:a:5::/64 showing up?

How can I fix it so this user can register, if I know they are not a spammer?

Hi attroll, welcome to SFS.

Ipv6 was formerly ratified as an Internet Standard on 14 July 2017, but it is only recently that SFS has begun to receive many questions about blocked IPv6 addresses. Whilst I've got a good personal handle onto the IPv4 address space I'm a bit deficient about the IPv6 address space. However, I'm catching up quickly due to having to handle all these new questions.

Here are a couple of information links:

Fundamental points:

IPv6 has 2^128 = 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses
The standard size of a subnet in IPv6 is 2^64 addresses
(thus a /64, and also the smallest subnet size available)
(a bit insane, since that is about four billion times the size of the entire IPv4 address space)
Stateless address autoconfiguration (SLAAC) requires a /64 address block
RFC6177 "recommends (ISPs) give home sites significantly more than a single /64". However, the early experience is that ISPs have handed out just a /64.

You will perhaps therefore realise why SFS deals with IPv6 on the basis of a minimum /64 block of IPv6 addresses. Essentially, for IPv6 a /64 is equivalent to the IPv4 /32 (the latter is just a single IPv4 address). Thus:-

…the evidence of the SFS database fundamentally disagrees with you. That IP address is currently rampant with spammers.

The question is.
Is there a way to set it up so that they can get past being block?
Or let that IP be allowed past the Spam-O-Matic on my site?
There are a lot of users that try to register on my site that are not spammers, but the Spam-O-Matic sends them the message saying they are denied.

I know pots & pots of stuff about SFS & nothing whatsoever about Spam-O-Matic.

You will need to ask that question somewhere else, attroll. Or stop filtering on IP Addresses (a good idea) and start filtering on email addresses (a great idea) instead.
