Solvemedia isn't going to work. Here is theymos' opinion about it:
Elsewhere, someone suggested Solvemedia, but I think that all captchas based on reading text are actually easier for high-quality OCR to solve than for humans. The photo-based ones give computers a major disadvantage over humans. I don't care very much if people use services like 9kw.eu to solve the captchas, since that at least has a cost, but if a captcha can be OCRed, then they have no cost at all, making them completely useless.
If someone has other suggestions for good captcha services/libraries, let me know. I don't really like using Google products, since Google's whole business model is spying on people. Though as I mentioned, I don't have much faith in captchas based on reading mangled text.
I can add to this that all captchas are solvable by bots using captcha solve services. People in third world countries working for $0.25 an hour fed through to the bots. reCaptcha is used because it is the most expensive at roughly 10x the price of others.
reCapatcha is fine if you don't use any VPN, proxy or TOR and you don't solve many of them. I restrict myself to no more than 5 a day and only ever have to tick the 'I'm not a robot' box and don't have to solve anything.
