I see two possible long-term solutions to the captcha problem
1) Ask user to do a relatively expensive computation. This can be done in the background while the user is typing his post.
2) Request a small amount of money (10c) per comment. Good websites will return the money to non-spam commenters, will keep spammer's money. This however requires working microtransactions.
- dchichkov 14y ago1) Asking a computer to do a computation is not such a great idea. Low powered devices (think iPads) running javascript would be at a great disadvantage to highly efficient botnet clusters that spammers own. 2) Requesting a small amount of money may work. Alternatively requesting a user to do some useful task (like Amazon Turk HIT) to get some funds.
- emiliobumachar 14y agoSome computations just cannot be parallelized. (Yet. I'd be ironic if spammers advanced the field of parallel computing) The speed difference for single processors remain, but that's a single order of magnitude, except in extreme cases.
- tripzilch 14y agoBut you can always parallelize the spamming itself.
