Like many of the people above, I'm still having this issue. I don't post on the forums, but I'm a regular visitor to the main site: as with others I'm using Chrome, AdBlock, no VPN. I am asked if I am a robot at absolute minimum once every time I visit the site, however over the last week it's started asking me about 10 to 15 times before it lets me in. This is then repeated every time I leave the site and return, and frequently just when changing pages within the site.

Edit: the full page recaptcha one, not just below posts as asked above.
