Same, but for VPN (either corporate or personal). Reddit blocks it completely, requires you to sign-in but even the sign-in page is "network restricted"; LinkedIn shows you a captcha but gives an error when submitting the result (several reports online); and overall a lot of 403's. All go magically away when turning off the VPN. Companies, specially adtechs like Reddit and LinkedIn, do NOT want you to browse privately, to the point they rather you don't use their website at all unless without a condom.
