How to make a bad-word filter?

Question

Hi, my site running out of CPU due to SPAM huge spam posts by Indian Spammers :( Almost thousand of spam posts like this "love problem solution in delhi, india +91-9680255300" has been posted just in 2 days :( and i have blocked many ip addresses with no success.

So, this could be a very good idea if we can make a bad-word filter, so if a user post contain "love problem" then the post will not publish.... Need kindly urgent help .. Thanks

* I am also using cAptha module.

You can do this with a filter plugin. Use the filter_question function then check $question['content'] for the spam keywords.
