I think (as a non-member of the mathoverflow community, I just flag spam here) that the spam flag fits perfectly. [e]xists only to promote a product or service, does not disclose the author's affiliation. The product in question is the article. The author (or someone else who likes him) has been spamming this article over 30 times so far. (Thats just ...

Rest assured that the moderators are well aware of this user and his sockpuppets. I have now placed this question under protection so that these entities cannot post further nonsense. The usual basins of attraction for this particular user involve RH, the Goldbach conjecture, the abc conjecture, and sometimes primality testing, and I have occasionally ...

There are now lots of similarly named accounts (having to do with car insurance) showing up in Recent Badges. I think they are effectively spamming in the Recent Badges space. Going back further, there is another set having to do with dentists in Dubai... I advocate for immediate destruction of such clusters of accounts, and broader network-level blocks ...

There aren't any rules against it. However, that doesn't mean that your company profile can go around posting links to your website/product in all your answers: the rules outlined in the help article on How not to be a spammer still apply. This means that you shouldn't link to your company website unless if it contributes to the answer, your affiliation is ...

I'm happy to hear what the community thinks, but my instinctual reaction would be to destroy it. The account has no business here and the page is meanwhile free billboard space: not something I think should be condoned.

I actually think that the "low quality" flag makes the most sense. I just reviewed and voted to delete a post marked low quality, and it was easy and fun. It's also good in that I think many people were hesitant to flag things as spam that weren't traditional spam, but there should be no disagreement about voting to delete things that are "low quality". ...

Any user with at least 15 reputation points should flag the post as spam. After 6 spam flags, the post is deleted. In addition to being deleted, even for users who can see the deleted posts, the content of the post is hidden - although they can still access the revision history. The same thing happens after a total of 6 flags that are either "spam", or "rude ...

The SEO trick won't work; for users with a reputation less than 2000, the link has a nofollow attribute, which makes Google ignore it for SEO purposes. According to this answer, you're allowed to create a 'company account' as long as you're the only one who is using it. The general stance of Stack Exchange on this kind of 'spam' seems to be that you can ...

Spam (i.e. commercial advertisements) should be flagged as such. -- Six spam flags delete a post.

In the past few days some well known crank has been posting a lot of junk, in particular some of it seem to be some sort of an attack on one of the most established users in this community. I feel strongly that we don't need to allow these posts to exist any longer than the minimal time it takes to delete them. But that would require the posts to appear on ...

IP blocking is already done automatically. Make sure to reject the edit for vandalism so that the right mechanisms are triggered. If you see repeated acts of vandalism on the same post, then also flag that post for moderator attention so that a human can look at it.

There is a new system in place (rolled out late last year) that protects from this sort of thing. It's fed off of the community and moderators taking normal actions, and it's global to the network. If users on Stack Overflow (as an example, all sites feed into and subscribe to it) reject edits as spam, they significantly impair the ability of the spammer ...

Yes. We've recently deployed a new spam blocking system that is partly fed by the signal that it receives from the community and moderators during the normal course of moderation, which includes getting rid of spam (and the accounts that post it). If you see obvious and blatant spam like that, flag it as such. Moderators should also destroy these obvious ...

If you can get and maintain a chat room going (e.g. here), you can simply link to the post there for your fellow users to review and flag. It's pretty effective.

By trimming the question down to half (until example with $\frac{1}{\beta-\alpha}$) I could post it and then edit it to full length without problem. The comments to my question indicated that this is legal behaviour here. I'm still wondering if it is a bad sign that the spam detector can be tricked like that, but as far as I'm concerned, I'm glad the ...

There is no clearly defined networkwide policy on this topic, because the rules on self-promotion only apply to posts, not user profiles. Your ‘About me’ is your own space, and as long as it’s not offensive to others, you can put there whatever you want. That said, it’s clear that this user is up to no good. I'm not sure if the ♦ moderators want to ...

On Physics.SE and Chemistry.SE we have a policy where non-mainstream science is not allowed. Non-mainstream is defined by "Anything that couldn't be published in a reputable journal". So a question/answer that proposes a new, non-mainstream theory is not allowed. We get a few of these every ~week (sometimes with a persistent user who eventually gets banned) ...
