... whoever manages / monitors this forum and removes the annoying spam health / medical rubbish which appears is doing a fantastic job.

This is for Ubuntu questions, not 411 spam.

Keep up the good work, whoever reads this.

This question came from our site for Ubuntu users and developers.

    (1) Q&A site, not forum. (2) That'd be us magical unicorns, sweeping every Stack Exchange site every minute of every hour of every day for spam. (3) What's 411 spam? – Nic Hartley Nov 2 '17 at 1:34

    @QPaysTaxes - 411 is "information", so 411 is "informational spam", like someone posting what they do for a living, or how they got free viagra. – rmustakos Nov 8 '17 at 2:38
  • Hi @HenryWHHackv2.1 I was not planning to change it. From my side, it was a generic "whomever does this...." point. At the time I wrote it I was utterly unaware of who or how this was taken care of, just that it was. I was not even aware of the "flags" for.... flagging. I simply had not seen them. I also did not know if it was "the likes of you....." performing an altruistic act of supreme sacrifice or some pseudo Mr. Charrington taking care of everything for us. But know I do know. And so do you. – Piloti Nov 10 '17 at 16:47

Not to put down Mithrandir's answer or Charcoal which indeed does a terrific job, but it's not only the awesome Charcoal folks and SmokeDetector who keep Ask Ubuntu clear of spam, it's also site moderators and normal users like you and me. Until recently, every spam post had to be flagged by six site users (with at least 15 reputation) or one moderator to be deleted. Now, many spam posts receive 3 automatic flags through a mechanism developed by Charcoal, but they still need flags from human users to be deleted.

If you see a spam post, please flag it! Most of them now disappear at lightning speed, but sometimes, for whatever reason, they end up hanging around for a while. It's up to the site's community to keep the site clean.

Ask Ubuntu is moderated by you.

    you should add that down-voting them is not ideal beforehand of flagging, this avoids sometimes charcoal and smoky to learn the pattern. – Videonauth Nov 2 '17 at 15:50

    @Videonauth lol, "Smoky", like Smokey the Bear! "Only you can flag spam" – wjandrea Nov 4 '17 at 1:44

    @Videonauth whether or not you downvote doesn't matter, Smokey will detect a post as long as the post contents are considered spam and the score is below the threshold (for most rules, this is a score of +1). Source: I am a Smokey dev – angussidney Nov 4 '17 at 7:43

You're welcome! ;)

We're an organization known as Charcoal, or Charcoal-SE. Check out our website https://charcoal-se.org for some amazing spam detection!

But seriously.... yeah, we're Charcoal, and that's our website. We detect spam all over the Stack Exchange network - not just Ask Ubuntu, but Stack Overflow, Super User, Math.SE, Bitcoin.SE, just to name a few, using a bot named SmokeDetector. Essentially, the bot fetches every single post that's been posted or edited on the network, and puts it through a series of tests - mostly regular expressions developed by users who noticed patterns over the years. All of our code is on GitHub, and we welcome all people who want to help us. Just pop into our chat room, Charcoal HQ ;)

If you're a statistics kind of person:
We've detected a little over 10,000 posts on Ask Ubuntu alone. Over 9,600 of those we determined to be spam. All over the network, we've detected 91,000+ posts, of which roughly ~74,000 were determined to be spam. That's... a lot. And you can find the content of these posts on https://metasmoke.erwaysoftware.com, where we keep them to help us in detecting common spammers and other patterns, and hopefully help us refine our spam checks to be even more accurate.

We're a volunteer organization, not officially supported by Stack Overflow, Inc. We do this because we don't like spam, and to keep browsing the site a better experience for users like you.

So:

You're welcome!
