PlayThru is good replacement for the google reCaptcha, like it is introduced in the forum thread:
I think, this is really nice tool to implement in my site since it is eye-catching and fun to use!
(Do ever google reCaptcha become FUN to use??)
I actually end-up playing the PlayThru, instead of signing up for the account.
(and still not having one)
But I still wonder if this is really help us to block spam bots? Or is this really easy to use (for developer)?
And also to think that this is much easier for the human spammer to post their spam messages...
What do you think guys??
Sorry I forgot the link to PlayThru, here it is:
