So is is possible to add a captcha to a paypal hosted donation button? We are a not for profit which takes donations and recurring donations via Paypal. We used to have a ton of people using us to test hacked accounts when we allowed single 1 dollar donations, we increased the minium to 10 to stop this, however we now have a bunch of people using hacked accounts and testing them with our recurring donation button for 10 dollars a month. Unfortunately a lot of our legitimate donors make 10 dollar monthly donations - so we don't want to break this, we rely on it. Is it possible to add a captcha or something to a paypal hosted button to make this more annoying to the hacked account testers so they go away?
