When you claim a gift, Fluxer asks for a captcha to make it harder for bots to claim gifts. Your device works out a small maths problem for it, which usually takes a moment.
Why does claiming a gift on Fluxer need a captcha?
When you claim a gift, Fluxer asks for a captcha to make it harder for bots to claim gifts, and it doesn't ask for a two-factor code. Your device works out a small maths problem and sends us only the answer, and you don't have to click through a puzzle.
No third-party captcha service is involved. On slower phones, working out the problem can take your device a little longer. Your account also needs to have an email address on it before you can claim a gift that someone else has sent you.
