That's a bit whack-a-mole..

There are other methods, including of course filtering, but it has really reached the ridiculous level

However, the list operator (Graeme) has asked that spam complaints stay off the list, so will keep this pretty narrow.

Gmail/Google is the most reported spam source, from everything from pure threat actors sending phishing, to threat actors selling fake services, to the SEO/Offshore development spam farms (mostly from India)

Each of these need a different tactic, but frankly Google/Gmail needs to be help accountable. Some of these threat actors operate with impunity for months.

I personally don't think any relief is in sight, unless RBL's start putting their IPs on notice.. See SpamHaus is willing to tackle the 'too big to block' operators lately.. Or if a global consensus to start holding them accountable.. or someone decides to launch that class action suit for damages..

A different forum for this discussion should be found.. As it is, I think most filters now penalize Google Groups and other Google services.. Could make Google 'filters' more public, but that just gives the threat sending secrets away, and they can change up quite quickly.

I am sure the spammers watch for changes in open source filters themselves.

We experimented with sending 4XX errors to see if this would be noticed, for known spammers, to no avail. And sending 5xx simply tells the bad guys to change methods.

And of course, now we have AI generated materials that are much harder to filter on, so at the end of the day.. this has to be dealt with at the source.

Sure wish the Google teams would interact more with the threat researchers..

Anyone else really hammered by seemingly freshly created endless variations of users @gmail.com sending out spam after spam after spam ? 1-2 paragraphs of text only random AI slop, no attachments, no nothing.


Bayes helps somewhat but the AI variations make it an ongoing battle


Is there some sort of global list for listing @gmail / @outlook / @hotmail addresses that do this sort of thing so we can all report them and use collective knowledge against these addresses ?
If not, what are you guys doing about them ?
