Spam spaM SpaM sPAm

Post by bubbathegimp » Mon Jan 07, 2019 3:19 am

About once every few weeks I get a New registered user from India Dot com, Hawking cheap Chinese Metal Detectors.
I finally broke down, and did the *@india dot com thingie in Ban E-Mail address, Which leads me to wonder...
Does anybody maintain a list of known E-Mail spam domains that would be of advantage to go ahead and add to the Banned E-mail doman list??!!

it is basically a waste of time. they will be back with a different email address/domain. they change them at will.

best thing to do is create a good A&A anti spam question/answer using the built in system in the admin panel.
that way, they won't be able to register at all and you will not have to deal with the spam.

The question is are you ready to even ban Gmail and other legitimate providers? I ask this as someone who tried going down that route. All of a sudden they switched tact and started using Gmail and other legit providers. At the end of the day they feel like they've won either way as they don't even believe that even a whole 1% of their spam sent out will get out there to be seen.

I understand that there are plenty of free Mail providers such as Gmail. Yahoo, Hotmail etc...
I am wondering about known domains that only serve as Spanners without typical public users??!!...,

There is some akismet plugin... but as lumpy said above (with a typo), Q&A questions are the best anti bot method out there. Custom, but easy, Q&A questions are better than google's captcha any day. You need a good bit of them to work, I'd say 5+. To be safe I'd make at least 7 or 10 but that's just me.

Please don't do this. If you start getting spam you have no way of telling which question was compromised. One is enough.

a list of known E-Mail spam domains
Almost nobody relies on the domain name alone and instead maintains IP addresses - have a read on DNSBL and Comparison of DNS blacklists. phpBB already uses those - check the manual 3.2.3.3, option "Check IP against DNS Blackhole List" to see if you have this enabled.

One of the few true lists of domain names only is https://www.spamhaus.org/dbl/.

I have a list of 2469 regular expressions alone to match domain names providing disposable email addresses (mostly used from this list having 14962 domains refined into a more robust format, along with additional entries). Does that give you an impression on how big a blocklist can get just for a tiny purpose?

Q&A questions
Question and answer questions? You mean Q&A pairs, and I too think it should be only one pair, not multiple ones.

Not only do you NOT NEED multiple Q&As, it is counter-productive. Your protection is only as good as your weakest question, and as kinerty says, when broken, you have no idea which one or ones are faulty.
