@mlanger@mastodon.world @gglockner@social.seattle.wa.us yeah that runs a few checks in JavaScript to try and make sure you are a person, but it wouldn't surprise me if it can be bypassed easily these days for someone who wants to. A lot of times they are checking if they have seen you before and detect mouse movements or other human interactions. They also check network requests to see if you are just downloading the HTML and skipping over things like images and scripts.
If something looks off they will usually do a captcha challenge instead of outright blocking. The 'not a robot' check box from Google recaptcha has been doing the same thing for years.

@mlanger@mastodon.world @gglockner@social.seattle.wa.us part of it is also to just slow down things for a little bit. Scrappers become expensive if you start slowing down requests at large scales.

@bhhaskin@social.bitsofsimplicity.com @gglockner@social.seattle.wa.us I'd sure like to do something on my site to prevent scraping.
