They recently removed User Agent and CSRF token from signature creation process. Right now used only rhx_gis parameter and URL decoded variables from query string to generate MD5 signature.
However, your findings about user agents looks interesting. I assume they may use user agent to generate rhx_gis. It could explain why auth doesnt work if you change single char in user agent.
Thank you guys for all these feedback for using website on mobile, we fixed index page, video should work now on phones, so as price list and also footer. And now fixing signup page for mobiles :)
thank you for your opinion, we noted it. By the way you are paying for using cloud resources, not for using technology, you can compile digger, download it and run for free at your own server or computer. And you can do it with free plan. So Im not really sure why we are discussing cost of our subscription plans :)
We are in beta, so we would really appreciate some feedback about user experiece when they using website, visual extractor, or compiled diggers.
Legal side of web scraping is heavily depends on country you live in.
It actually depends on what you going to do with your knowledge, Go is definitely more efficient and faster than Python, on other hand Python is more popular, easier to use, has bigger set of available libraries.
