Repeated notifications when posts auto-flagged for spam


(Jacob Hoffman-Andrews) #1

I recently got 11 messages from “system” on my forum indicating a single message had been auto-flagged for spam. It was the top message in this thread: Fedora webserver https setup - Let’s Encrypt Community Support.

I also got 10 messages from “system” about another auto-flagged message, /root/.local/share/letsencrypt/bin/pip: No such file or directory - Server - Let’s Encrypt Community Support.

Neither of these was actually spam, but that’s not a big deal. I’ve adjusted the spam host threshold. However, it’s weird that I got so many duplicate messages about it.

I am guessing a new user posted the same link a bunch of times? I don’t see ten duplicate flags in your flag history? https://community.letsencrypt.org/admin/flags/old

Discourse does not like new users who create a new account and post links to the same domain over and over out of the box – it’s considered risky, spam-indicative behavior.

You can adjust the threshold in the site settings, of course.

We actually just got this for this very post

1 Red notification + 2 Green notifications for a single post … seems like we are overdoing it some.

It looks like you replying triggered it too @sam so might be a bug.

(It is actually considering all posts from a TL0 user with that domain as flaggable, 4 posts, 4 auto flags if they all contain the repeated domain)

Yep, agreed there are not ten duplicate flags, but there were ten duplicate messages. They show up in the ‘moderators’ section of the messages panel of the Let’s Encrypt forum.

I see, another cause here is the user posted logs but not as code blocks and those logs contained tons of URLs which were viewed as repeated links, aka spammers.

Also, at least one person whose messages were auto-hidden by the system as spam got multiple automated messages saying “Multiple community members flagged this post before it was hidden,” which isn’t true: it was just system that flagged his messages for spam.

To be clear, I have no problem with the “too many links” rule. I think that’s quite reasonable. But it seems like there may be some issues with how messages get sent out when it’s triggered.

If you’d like to poke at the messages in my account on https://community.letsencrypt.org/, feel free.

In general new users who dump a ton of URLs in posts, erroneously or otherwise, are going to have problems. For now probably best to just relax the site settings around new users and URLs in this particular case with this particular audience.
