Hey guys, Just realised that my previous email might have been blocked due to the attachments. I moved them https://www.dropbox.com/s/iat2zoq3ive772m/UserAgent-doctrine.PNG?dl=0 and https://www.dropbox.com/s/o2nm97k0eiwzqyc/UserAgent-Facebook.PNG?dl=0
Are you aware of the UserAgent blacklist problem? Cheers, Lucian On 17.

For the “doctrine.fr<http://doctrine.fr/>” website it is quite easy to see that it’s an actual blacklist : Using the Firefox user agent: curl -L 'https://www.doctrine.fr/' -H 'User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/603.1.30 (KHTML, like Gecko) FxiOS/1.6.0 Mobile/14E269 Safari/603.1.30 _id/000002' | grep incompatible_browser__link ->>> they return the “incompatible_browser__link” element Using the Chrome user agent: curl -L 'https://www.doctrine.fr/' -H 'User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/603.1.30 (KHTML, like Gecko) CriOS/1.6.0 Mobile/14E269 Safari/603.1.30 _id/000002' | grep incompatible_browser__link ->>> they DO NOT return the “incompatible_browser__link” element Using a random user agent: curl -L 'https://www.doctrine.fr/' -H 'User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/603.1.30 (KHTML, like Gecko) QQiOS/1.6.0 Mobile/14E269 Safari/603.1.30 _id/000002' | grep incompatible_browser__link ->>> they DO NOT return the “incompatible_browser__link” element The doctrine.fr<http://doctrine.fr/> case might not be critical but it seems that Facebook is starting to do a similar thing - please check the attached screenshot (not sure if in this case its a blacklist or white list). I was wondering if there is already anything in place to fight/prevent this. Thanks! Lucian <UserAgent-Facebook.PNG><UserAgent-doctrine.PNG>
