This is explained in the blog post:
> There's always the option of just parsing server logs, which gives a rough indication of the kinds of traffic accessing the server. Unfortunately all server traffic is generally seen as equal. Technically bots "should" have a user-agent that identifies them as a bot, but few identify that since they're trying to scrape information as a "person" using a browser. In essence, just using server logs for analytics gives a skewed perspective to traffic since a lot of it are search-engine crawlers and scrapers (and now GPT-based parsers).
And the real benefit of this trick is separating users from bots.
That you cannot access the logs because you don't own the servers doesn't mean there aren't any servers that have logs.
No. The most obvious way is to reassess running on servers/services that you don't own, and which don't offer features you need.
