Thread:Project:Support desk/How do I enable the edit throttle/reply (2)

Dear Ciencia Al Poder,

Thank you for the recommendation to try QuestyCaptcha. After I switched from ReCaptcha to QuestyCaptcha with a long list of home-grown questions, I got *much* less spam.

As you guessed, I -- as recommended at at memcached -- don't have memcached installed.

I am curious: Why do these rate limiter / edit throttle extensions require memcached? Would it make make any sense to write a new rate limiter / edit throttle extension that did not depend on memcached?
