Our Devs have now implemented a "prove you're a human" CAPTCHA for our direct card-payment checkout screens, which we can enable by request for any seller account. Please contact us if you would like us to enable this for your account.
We have already enabled the CAPTCHA for sellers who previously contacted us about apparent "carding" attacks (automated bulk-testing of stolen credit card numbers) through their E-junkie purchase links; if you are one of these sellers, you should have received a message from us confirming this earlier today.
Adding a CAPTCHA is the industry-standard recommended solution to fend off such automated carding attacks. With the CAPTCHA enabled for your E-junkie account, most legitimate buyers should simply need to tick a checkbox to confirm they're a human, but any suspicious-looking activity patterns would present a more challenging test to complete checkout.
