Why Captchas have gotten so difficult
The issue isn&#x27;t just that humans struggle with them or that bots are getting better or what not, it&#x27;s because there&#x27;s no way to make a captcha that works across multiple websites like a standard &#x27;library&#x27; and expect it to remain uncracked. Anything that becomes common will be attacked and defeated, because there becomes a financial incentive for spammers and no gooders to do so.<p>The solution is to make captchas that are bespoke to each site, since it means the same bot or script can&#x27;t be used on every one and spammers have to go out of their way to crack each one. You can already see this right now; sites with their own systems generally get no spam at all.<p>But given that most people aren&#x27;t programmers, well it means they&#x27;re stuck with mainstream captcha systems which present a giant target to the internet&#x27;s never do wells.<p>Niche sites can avoid the issue with topic specific questions though.
