The blog Its FOSS has 15,000 followers for its Mastodon account — which they think is causing problems:
When you share a link on Mastodon, a link preview is generated for it, right? With Mastodon being a federated platform (a part of the Fediverse), the request to generate a link preview is not generated by just one Mastodon instance. There are many instances connected to it who also initiate requests for the content almost immediately. And, this “fediverse effect” increases the load on the website’s server in a big way.
Sure, some websites may not get overwhelmed with the requests, but Mastodon does generate numerous hits, increasing the load on the server. Especially, if the link reaches a profile with more followers (and a broader network of instances)… We tried it on our Mastodon profile, and every time we shared a link, we were able to successfully make our website unresponsive or slow to load.
It’s Foss blog says they found three GitHub issues about the same problem — one from 2017, and two more from 2023. And other blogs also reported the same issue over a year ago — including software developer Michael Nordmeyer and legendary Netscape programmer Jamie Zawinski.
And back in 2022, security engineer Chris Partridge wrote:
[A] single roughly ~3KB POST to Mastodon caused servers to pull a bit of HTML and… an image. In total, 114.7 MB of data was requested from my site in just under five minutes — making for a traffic amplification of 36704:1. [Not counting the image.]
Its Foss reports Mastodon’s official position that the issue has been “moved as a milestone for a future 4.4.0 release. As things stand now, the 4.4.0 release could take a year or more (who knows?).”
They also state their opinion that the issue “should have been prioritized for a faster fix… Don’t you think as a community-powered, open-source project, it should be possible to attend to a long-standing bug, as serious as this one?”

…and here I am, running a blog that if it gets 15k hits a second, it won’t even bat an eye, and I could run it on a potato. Probably because I don’t serve hundreds of megabytes of garbage to visitors. (The preview image is also controllable iirc, so just, like, set it to something reasonably sized.)
Wait, you’re going to tell me you don’t actually have to serve bloat on a blog like it’s foss? No way!
I only serve bloat to AI crawlers.
map $http_user_agent $badagent { default 0; # list of AI crawler user agents in "~crawler 1" format } if ($badagent) { rewrite ^ /gpt; } location /gpt { proxy_pass https://courses.cs.washington.edu/courses/cse163/20wi/files/lectures/L04/bee-movie.txt; }…is a wonderful thing to put in my nginx config. (you can try
curl -Is -H "User-Agent: GPTBot" https://chronicles.mad-scientist.club/robots.txt | grep content-length:to see it in action ;))Your bandwidth bill lol
I don’t think serving 86 kilobytes to AI crawlers will make any difference in my bandwidth use :)
Oic its a redirect now
It’s not. It just doesn’t get enough hits for that 86k to matter. Fun fact: most AI crawlers hit
/robots.txtfirst, they get served a bee movie script, fail to interpret it, and leave, without crawling further. If I’d let them crawl the entire site, that’d result in about two megabytes of traffic. By serving a 86kb file that doesn’t pass as robots.txt and has no links, I actually save bandwidth. Not on a single request, but by preventing a hundred others.deleted by creator
Or serve a gzip bomb (is that possible?)
