We're sorry you're having problems, however a few things:

- The system that would show Captcha's sits in front of the website, it isn't part of it, so it has no idea if you are a free or paid member, logged in or not. It is designed to identify non-standard browsers or browsers that don't have JavaScript loaded or fast page loads to detect non-normal behavior to prevent data mining (yes, people have tried).

- This system has been in place for a couple years, and nothing has changed with it recently.

- Certain VPN providers use known abusive data centers as their VPN exit points so that alone will trigger a Captcha (again, as has been the case for a couple years).

- A large amount of quick page loads (of any page) may trigger a captcha.

- When you do solve a Captcha, it should be good for at least 15 minutes. If you get a captcha more often than that, there is an issue with your browser or an add-on (as noted below).

- There is no such thing as a "double captcha". The issue you are describing is caused by one of your browser plugins blocking the cookies and/or JavaScript from our domain which will cause the captchas to happen more often.

- We know that uBlock Origin pushed an update that incorrectly is blocking more of our Javascript beyond ads, so please white-list "expertflyer.com" in uBlock or similar add-ons.

- ....... Plus also recently pushed an update that now has an "Block additional tracking" option. If enabled try turning that off. (We know that ....... normally does not interfere with ExpertFlyer).

- Some browser add-ons change the user-agent string of the browser, making it non-standard. This will also trigger the captcha. This should be turned off for ExpertFlyer.com (again, this has been the case for years).

- If you still need help after taking the above steps, please email us directly at [email protected] with your account information along with the exact trace string from the bottom of the captcha page, your IP address, your browsers user-agent string (What's my user agent?) and a list of browser add-ons you are using.
1. If you look above you will see the complaints are not just from me on this issue.
2. I surf the web all the time a lot, around the world, different wifi sources different VPN servers (though same VPN provider) and it is only your website "that complains". This happens on PC and Phone (same VPN provider though)

I realise you could have a mere $8 a month subscription and get huge amounts of data for that via bots, and that is a risk. But a risk easily mitigated post login (if too much data is asked for at a fast rate) not just because your scripts don't match
