Source Site Blocks Collection: What Telematic Does
We analyze what happens when a content source technically blocks auto-collection and why this does not always mean a loss of material for the project.

Sooner or later, anyone who sets up automatic content collection from external sources encounters this: yesterday, the feed reliably brought articles, but today the source suddenly falls silent. The first thought is usually panic — "the source is broken, that's it, the autopilot has stopped." In practice, in nine out of ten cases, this is not a malfunction but a website protection mechanism: it simply detected not a human browser but an automated request and decided not to deliver content.
The difference between "the source is truly unavailable" and "the source is temporarily protecting itself from bots" is fundamental. In the latter case, the system should not give up after the first failure because behind the same block can be anything from a simple timeout to an advanced anti-bot system that checks browser behavior. At Telematic, we built our content collection with precisely such situations in mind, rather than an ideal world where every site always delivers clean HTML on the first request.
Below is how this works internally and what it means for someone who just wants fresh material to arrive in their project every day, rather than endless errors in the launch log.
Most websites, especially news and industry sites, have long lived under the pressure of bots: some steal content, others inflate traffic, and others simply overload the server with frequent requests. The industry's response is multi-layered protection: from simple request limits from a single IP to complex checks that analyze whether the "visitor" behaves like a real browser — executing JavaScript, moving the cursor, loading fonts and images in the correct order.
For an auto-collection system, this means that one cannot rely on a single method of obtaining a page. What worked yesterday may be blocked tomorrow — not because the source has closed, but because the protection has become stricter, or the system noticed a pattern of requests and temporarily flagged it as suspicious.
This is why content collection at Telematic does not stop after the first failure but sequentially goes through several levels of page retrieval before declaring the source truly unavailable:
Only if the material cannot be obtained at any of these levels is the source marked as temporarily unavailable, rather than "permanently broken." This is crucial: a one-time network failure or temporary block should not reset a source that has been functioning properly for months.
Getting the page is only half the job. Next comes the thematic content filter: if a theme is set up in the project, the system filters out materials at the project level that formally came from the source but do not fit the context — for example, an industry feed suddenly publishes a promotional press release or material that is off-topic for the channel. This happens before the content enters the costly AI processing, saving both tokens and the attention of a person who would otherwise sift through "off-topic" drafts.
What passes the filter is then checked against auto-analysis thresholds: the system itself decides which materials confidently meet the project's criteria to automatically proceed further down the conveyor, and which remain drafts for manual review. This is not a binary switch of "trust the source or not," but a configurable confidence boundary that allows for the automation of obvious cases while leaving the decision to a human in contentious situations.
We had a telling case during testing: one of the industry sites, which had been reliably providing material for several weeks, suddenly stopped delivering anything but a placeholder with a captcha in one day. The first reaction was to write off the source as dead and remove it from the project. But upon checking, it turned out that the site had simply implemented stricter protection after a wave of mass scraping from some third-party services — everyone who accessed the site automatically, including us, was affected.
It was the multi-layered approach that saved the situation: the simple request indeed stopped working, but the browser emulation continued to retrieve the page normally because the protection primarily cut off the most primitive requests without signs of a real browser. If the system had given up after the first level, the source would have been unjustly categorized as "unavailable" — while the material continued to be collected smoothly.
There are also reverse situations: at some point, a source implements protection so severe that no level passes. In such cases, the system honestly records the source as unavailable, instead of endlessly "knocking" on a closed door and wasting resources on it. This is also a conscious choice: it is better to clearly show in the launch log that the source requires attention than to mask the problem with endless silent retries.
The practical takeaway is simple: if you see a single failure in the source's launch log today, it is not yet a reason to panic and move the entire feed to another service or manually recheck the settings. The system has already gone from a simple request to advanced bypass before reporting a problem — meaning that by the time you see the error, it is indeed worth taking a closer look at the source.
It is advisable to set up the thematic filter as accurately as possible from the start — this saves not only time on manual moderation but also tokens that would otherwise be spent on processing off-topic materials. And it is better to initially set the auto-analysis thresholds conservatively and gradually loosen them as you see that the automatically accepted content truly meets expectations — this way, the autopilot gains trust gradually, rather than with one abrupt switch.
Ultimately, the task of this mechanism is to relieve the person of the routine burden of "checking if the source is still alive," leaving them only with substantive decisions: whether the material is worth publishing, whether the tone is appropriate, and whether manual editing is needed. Everything related to the technical availability of the site, the system strives to resolve itself before bothering the project owner.
