[...] self as a human is still a problem which can lockout some users. Additionally CAPTCHAs fail if humans and not bots are used for spamming. I still consider Akismet to be a better solution. Akismet uses the community to identify spam [...]

[...] I think it is great. In my opinion spamming exploits a loophole in the current search engine algorithms, since they are purely link based. Human contribution to these algorithms can fix these loopholes and probably work as the best solution for spamming. ChaCha is another search engine which has contributions from humans, but in a different way. [...]

[...] This can also be considered to be the reason behind all the spam. Spammers try to insert links to the target website so that its pagerank increases. I think, just like other metrics even the pagerank is just an indication of quality and can be manipulated. This algorithm assumes that linking will happen out of liking of a web site, but this can be manipulated using spamming and programs like link exchange.

Though a single spammer cannot be as fast as a machine, thousands of them together than spell a lot of trouble. Captchas force you to identify certain characters and enter them, which machines cannot follow. This works fine assuming that humans, for whom captchas are built, do not spam. The outsourcing trend will overcome this. [...]

That’s incredible! I still approve every comment on my blog and it’s incredible the volume of SPAM I receive, even with Akismet. I have had much more luck with contact form spam by implementing a “challenge question”. I wonder what the success of outsourcing would be on challenge questions which require comprehension and familiarity with the website.
