I’m not a web man, a master of webs, a dominator of the masses if you will, but I assume they keep the information to track engagement rates by country or to hand over to the feds if some anonymous guy is openly talking about shooting up a school and they need to catch ‘em real quick. That’s probably a standard practice. I think even Null hands over that info if the feds ask for it.
If not, just lemme know. I like learning about this stuff and this is just a guess.
I'll explain quickly:
Every web request you make will go through a webserver at one point, and access-logging will be enabled by default. This collects things like the IP address of the request, the URL of the request, the user agent, time - small stuff like that.
There's nothing
forcing the owner to keep access logging enabled*. There are times and places where it can be advantageous though. For example, if some retard is constantly signing up new accounts and posting illegal stuff. Or maybe you're getting blasted with insane amounts of traffic and need more info on what's going on.
Most of the time you don't need to disable access logging. There are tools you can run to anonymize the IP address (IE replacing the last octet of the IP address). If you do need to enable it, you probably don't need to keep logs for more than a day or a week at most.
* A court order would change your mind sharpish. To be fair, if someone is posting turbo-illegal shit on your tiny mastodon instance then you won't find many objections if you proactively reach out to authorities.
track engagement rates by country
This would be handled by analytic tools like google analytics. There are far better FOSS tools like plausible/umami too.
I think even Null hands over that info if the feds ask for it.
He'd be a moron not to but kiwifarms isn't really that comparable to a hobby mastodon instance. He probably gets more abuse reports in a week than most people will see in a lifetime.
This got a bit more into-the-weeds than it should be because... it's silly - it's expected for sites to log requests. I'm just being a nitpicking autist about it.
