Any DNS resolver libraries have a 4.5 second timeout? Maybe their infrastructure is just rotting.

It'd be weird that it's limited to specific outbound domains in that case.

domains load balanced across different servers in some overly complicated distributed topology with only one of them busted?

although seems unlikely it just happens to be the NYT.

That's what "random 10 out of 67k sites" gives you. Your set was cherry-picked, dang's wasn't. That said, dailykos.com seems to be banned. Happy now?

Definitely not random, in any case.

Nobody claimed that. You merely stated that "I don't see a single left-wing new source in there." and I offered a counter-point.

> having one left-wing source vs a ton of right-wing one doesn't achieve that

I didn't do an exhaustive search for "left-wing domains" that are banned to present you a complete list, this was attempt 1 of 1.

Following your model, I could claim that 100% of left-wing domains are banned, but I won't.

What is it if the information is freely available, to anyone asking, for a single domain they are trying to post at that time? It’s not secret, because they’ll be provided an answer if they email the mod team. It’s not free as in open source, because it isn’t available for anyone to download and study in full. So, since it’s not secret, is it public, or private? Since it’s not published in full but any query of LIMIT…

That encourages switching to another domain for spammy submissions.

That’s not going to work, because now that’s an API for spammers to bulk process against a domain list. The only available API must be human communication to the mod team, or the spammers will overcome it with automation.

Spammers can already do that API call and see if the domain shows up. This only puts human users at the same level of consideration as spammer automation.

There are a number of reasons this could be that are not necessarily nefarious. It's odd to jump straight to "something evil is going on" Tell me this, does Twitter have some kind of "play nice" code that slows down inbound clicks through to a site so it doesn't DDOS other sites? I can easily imagine a scenario where anti DDOS caode would allow small sites to pass through quickly, yet sites under heavy "click through…

This wouldn’t reduce total requests made so it would be a weird anti-DDOS measure.

Indeed. A five seconds delay only means the DDOS starts five seconds later.

It’s about 4.5 seconds for me https://imgur.com/a/qege0O9

glibc defaults to 5 sec, but the server wouldn't need to resolve the redirect domain -- that'd be the client's job. Unless it's doing so for some proprietary reason, of course.

Or did you mean failing to resolve some internal service's hostname?

Could it just be rotting infrastructure? I.e there is some logic on most visited domains to allow ease of moderation, that logic is read heavy and is now bucking under skew. Or even like some junior dev removed an index

A few years ago I remember their URL shortener on android app directing somewhere that my hostfile adblocker would catch (like an analytics domain or something). This made it so first click on certain twitter links would fail, but if I clicked it again it would go successfully. Ultimately I never researched it deeply enough but my guess is they had some sort of handler that would log whether loading their analytics s…

I've experienced similar behavior on iOS, not sure if it still does that though.

Seriously dedicated spammers can, yes! But antispam is about reducing the noise threshold, and eliminating low-effort spam opportunities that can be done to a single HTTP endpoint with a bash script is a big win. Simply having to access two pages is already too much to bother with for the vast majority.

Then click delays would appear random to any single client.
