Is it possible to deny publication of a topic with censored words?

[empleojovenes]

Well,

I will first explain why we need this feature. We are trying to avoid spamming in the forum so we tried image validation but it didn't work. Also tried recaptcha, I think it works much better, however its a bit difficult for our users to 'guess' the 2 words proposed. So I'm trying to find another way to avoid spamming.

All the content of the forum is completely in spanish, and the spam is always in english. So we would need a mod that denys publication of topics in english . I suppose it doesn't exit, so I though about censored words, a list where we could add some of the typical spamming words (free, sex, etc.). Considering that list, if a topic contains at least 5 censored words, publication should be denied, not just replace words with ****.

I searched within mods forum, but I didn't find anything similar to what we want. Any suggestion would be appreciated.

Thanks.
