In fact, I would choose this method as a last resort. It is much better to use Spam Defense if you have an active license. Or Cleantalk plugin if your license has expired. That kills 90% of spammers. Then use the link filter and set all posts that contain links to pre-moderation. This is a robust concept that will easily and effectively keep spam out of your community.

Why do you think so? If you consequently delete their content or set everything to pre-moderation, then you can. Spammers do not spam to just annoy you. That is not their goal. If their content is not seen or just for a short period of time, they will stop. As this will not make sense for them. They have to be “efficient” too. You just have to be a little more persistent as them. 😉

A self-hosted community has over 300,000 users registered over the years. I assume that at least 30% of email addresses are no more valid. It means I must manage e-mail bounces to proceed with bulk mails. I am going to switch from Google to Amazon SES/SNS. I have found two solutions: https://www.deschutesdesigngroup.com/portfolio-item/aws-simple-email-service-with-bounce-management/ https://ipb.silvesterwebdesigns.com/file/9-mail-bouncer/ Do you have experience with one or another? Which one would you recommend recognizing, marking and excluding bounced email addresses from the bulk mail recipients in IPS?

This. SEO is like a good fuel. The community is the car. But the fuel is useless if the car itself is a piece of junk. 😉

There is a difference. AI-generated content without human review is mostly garbage, not helpful and frowned. AI-generated content with human review and fact check is state of the art. 😉
