Around 1 year ago we got hit badly on our [blogging platform][0] by people/groups submitting fake customer support description of other big companies, either being Microsoft, Facebook, Comcast etc. Rolled out a machine learning model and trained it on the database. 99% of them vanished. Next day, the machine didn't work and success rate was around 5%. Found out, they have learned the trick and now using symbols from…

When we had this problem, we added an input element positioned off-screen and ignored submissions that populated it. Cleaned it all up.

The internet is not moderated in any useful sense for content. Drug markets like white house market, and before that silk road have perpetuated for years. Tor and other darknet websites host content that is nearly universally disdained by governments and even most individuals, which I hesitate to even name here what that heinous content is (you and I both know some examples). > We assume NASA's site has NASA-posted c…

>The internet is not moderated in any useful sense for content. Drug markets like white house market, and before that silk road... You mean the Silk Road that the US government "moderated" out of existence, along with other Tor marketplaces over the years? The same ones that suggest White House Market's existence is also likely to be limited?

I suppose in the sense that Gabby Pettito was moderated off the internet, Ross Ulbricht was moderated off of the internet and into a cage permanently for the heinous crime of facilitating voluntarily peaceful trade. Tor marketplaces were definitely not gone for years, the same content just moved under new banners. You can literally find the same content and more on WHM today as you did under Ulbricht's banner before he was kidnapped by government thugs.

I built a Python library for finding strings obfuscated this way. Was critical when moderating our telegram channel before an ICO. https://github.com/wanderingstan/Confusables E.g. "𝓗℮𝐥1೦" would match "Hello"

You should post this to Show HN. Also you have a typo on your README ("characgters")

The one built-in to Python will get you most of the way there:

    >>> import unicodedata
    >>> unicodedata.normalize('NFKD', '𝓗℮𝐥1೦𝗵𝗲𝗹𝗹𝗼')
    'H℮l1೦hello'
Obviously it isn't going to remap leetspeak characters like 1 -> l but it covers a lot of cases.

Here's a thought. Have a platform where identity is verified. Users can post publicly or within their circle. Any illegal or fraudulent content can be handled by the legal system due to the lack of anonymity. Beyond that, let users form groups for topics like reddit. Where does this fall down?

What I'd like is something identical to Facebook (preferably hosted in a box on my desk) that I invite all my friends to, and they have the ability to invite people to. 2nd gen is probably far enough. Anyone cuts up rough, I go by their house and make them miserable.

You never plan to have any friends beyond your immediate neighborhood?

For adversarial problems like this, a shadowban approach can sometimes be necessary. Perhaps people can still see their blogs but GoogleBot gets blocked from indexing them, or they only appear to someone with the spammer's cookies. That way it takes them longer to catch on and evade the model. Of course, that means you'll need to at least spot check your bans because you can't rely on legit users escalating to you.

Yep, shadow ban was in place as well. The thing is, the people that weren't the ones posting the content. It appeared their computer was affected by some type of malicious file to be part of a bigger network. (botnet?) I could see from the thousands of different IPs in different countries around the globe, that it could be affected personal computers. Very few of them were computers from hosting companies, the rest w…

Yup they utilize "residential proxies" to hide their behavior which makes the situation worse because sometimes it will affect your legit users

I'll fly in if need be.

I always read "dead" comments. I believe that many of them should not have been "killed".

Reddit rule of thumb: the downvoted comments are far more likely to introduce a new idea than the upvoted ones. However, it's like comparing the likelihood of dying in a car crash instead of a plane wreck: both events are rare enough as not to be worth considering in planning your daily life.

I often find material of value in dead comments. I think it's worth considering; I recommend it.

Did they map to ISP ASNs? Country geolocation doesn't say much anymore since there's so many VPN providers whose business is to buy a CIDR in every country and resell access.

Yes, almost all of them mapped to ISP ASNs.

Very few of them were from AWS, OVH and other hosting providers, very very few.

We ran each IP towards black lists ips, paid IP reputation checkers. Majority of the IPs were clean.

Back then we had IP reputation check, but it was a headache to maintain, so we disabled it later, however that time very very few them got stopped at IP reputation checks.

This article opens up with an anecdote about policing morality and imposing one's own local norms on the legal speech of others. NSFW is a euphemism. Please don't push your American puritanical worldview on every user of your UGC platform.

If they own the platform, why shouldn't they get to make the rules?

Legally, they are within their rights to.

Practically, it makes them an asshole.

Just because you are legally entitled to do something doesn't mean it's good for your users or society: e.g. the widespread practice of IAPs, or Apple's censorship of the App Store.

If you can identify text written with mixed glyphs just ban it outright. Normal users don't use text like this, the pure binary presence of such "homomorphic" text at all is probably a better signal for spam than whatever your neural net when running it after normalization.

> Normal users don't use text like this Sounds like you live in a filter bubble. (╯°□°)╯︵ ┻━┻ (ﾉ◕ヮ◕)ﾉ*:･ﾟ

I know right? There are so many times when I've wanted to use something like box drawing unicode characters (cp437) to explain a complicated concept on hacker news, but alas I couldn't, due widespread computer fraud and abuse. How are we going to build a more inclusive internet that serves the interests all ALL people around the world, regardless of native language, if the bad guys are forcing administrators to ban unicode?
