Developer Sammy Straus says his website became slow after he posted his feed reader to Hacker News, with automated requests contributing to the load. He traced a large share of requests to a website-monitoring service that summarizes changes for an AI newsletter, then added rate limits and other infrastructure improvements. The report does not provide traffic totals or independently verify the bot identities.
Developer Sammy Straus says automated traffic slowed his website after he posted his feed reader, sprinklz.io, to Hacker News about a month before writing about the incident. Straus attributed a substantial share of requests to an unnamed service that monitors websites and summarizes changes for an AI newsletter, and said he blocked it and made further infrastructure changes.
Straus wrote that the Hacker News post received about 100 upvotes and brought attention to sprinklz.io, a customizable feed reader that lets users filter topics such as AI and large language models. He initially thought the site’s slowdown reflected a normal increase in human visitors. But, he said, the performance problems continued and worsened several days after the post, while the activity he could observe did not match the number of logged-in users.
To investigate, Straus added logging to count requests by endpoint and reviewed aggregate NGINX logs. He reported that many requests did not fetch news articles and that nearly half of the traffic came from one user, which he identified as a service describing itself as monitoring websites and producing AI-generated newsletter summaries. Straus said it queried his site many times per minute. He did not identify the service in the post.
Straus said he blocked that source, added a robots.txt file to discourage some automated crawlers while allowing search-related traffic, and put rate limits in place. He also mentioned requests from recognized crawlers and vulnerability scanners, including probes for WordPress-related paths on a site he said was not built with WordPress. He wrote that he made additional infrastructure improvements over the following weeks, but did not publish performance measurements or request counts.
When Crawlers Overload Small Sites
The account illustrates how automated visits can affect a small website even when human interest in a post is relatively modest. A service repeatedly checking for changes may create substantial server demand, particularly if a site is not configured to handle frequent polling. In this case, Straus said the site’s load seemed out of proportion to its logged-in audience, prompting him to examine request patterns rather than treat the slowdown as ordinary popularity.
The episode also shows the limits of a single site’s defenses. Robots.txt is a request to crawlers, not an access-control mechanism; the post does not say that every crawler followed it. Rate limits and blocking can reduce unwanted requests, while infrastructure changes may help a site handle legitimate surges. For site operators, the practical takeaway is to distinguish human usage from automated traffic using server logs and endpoint-level monitoring.
The report does not establish that AI services generally caused the slowdown, or that all automated traffic was harmful. Search indexing and other crawlers can serve useful purposes. The issue Straus describes is the volume and frequency of requests from particular sources, and the lack of published measurements makes it difficult to compare the impact with other incidents.

A Feed Reader Reaches Hacker News
Sprinklz.io is a free customizable feed reader Straus has worked on for several years. According to his description, users can tailor what appears in their feeds, including filtering out topics such as AI or LLMs, and can create other customizations. The Hacker News post served as a demonstration of that filtering feature, he wrote.
The site’s traffic problems did not appear, in Straus’s account, as a short-lived spike immediately after the post. He said the service remained slow and got worse several days later. That timing led him to compare request logs with the site’s human activity. He described his investigation and subsequent improvements in a personal website post; the available account does not include access to the underlying logs or a response from the unnamed monitoring service.

Traffic Counts Remain Unpublished
Straus did not provide total request counts, server-load figures, or a measured before-and-after performance comparison. His estimate that nearly half of the traffic came from one user is not accompanied by a defined time window or a breakdown of how traffic was counted. The account is his interpretation of server logs; the logs themselves are not included in the source material.
The monitoring service is unnamed, and the post does not include a response from it or independently confirm the service’s identity and behavior. It is also unclear how much of the slowdown was caused by that source versus other crawlers, vulnerability scans, human visitors, or limitations in the site’s infrastructure. Straus said he added rate limits and infrastructure improvements, but did not state how much traffic was blocked or whether the changes resolved all performance problems.

Monitoring After Infrastructure Changes
Straus said the infrastructure work took place over several weeks and was intended to deliver performance gains for users. His report does not set out a public timetable for further changes or promise a specific capacity. The next evidence of impact would be updated measurements showing how the site performs under comparable traffic and whether automated requests remain a major source of load.
For readers interested in the product, Straus said sprinklz.io is available free to use. No additional statement from the monitoring service or independent analysis of the traffic was included in the material available for this report.

What source did Straus associate with nearly half the traffic?
He said an unnamed service that monitors websites and summarizes changes for an AI newsletter accounted for nearly half of the traffic. The post does not identify the service or provide the underlying logs.
What steps did he take?
Straus said he blocked the service, added a robots.txt file, introduced rate limits, and made further infrastructure changes over the following weeks.
Did the changes fix the slowdown?
The report says the changes were expected to improve performance, but gives no before-and-after measurements or confirmation that all performance problems were resolved.
What is sprinklz.io?
Straus describes it as a free, customizable feed reader that lets users filter topics and create other changes to their feeds.
