Also, I'm using Falkon browser every day - ever heard of that? I have to switch user agent to be allowed in some places which is ridiculous.
It may be profitable to use CAPTCHA for AI training, but that's not only annoying, it's also unethical because one (like me) may be unwilling to engage in such activity. Also, CAPTCHAs involving houses, number plates or bikes are absolutely invading someone's privacy.
Owners of websites (e.g. shops) themselves have more options to show captchas only in critical moments: when performing heavy searches, registering, checking out, posting. Again, it doesn't have to be intrusive or disruptive. But I understand this way takes more professional approach and probably requires programming, which is not what _every_ store owner can probably afford.
Probably because it takes fractions of a cent to solve those grainy distorted captchas?
Whereas its not so trivial to get an extra IP address, extra computer, etc.
I can’t think of any alternative that would still be as onerous a bar to spammers and bots but also be less restrictive for genuine users. Other then linking real IDs, which has its own can of worms.
