Word Filters auto-ban feature suggestion

Hello,

Right now, with Word Filters, you can reject on a keyword. I do this, but it tells the spammer the keyword, so if they are any good at their corrupt line of work, they avoid the word and post again.

Hiding posts doesn't do the job because then I get thousands of spam messages, hidden from users, but deleting them all is still a lot of effort.

What I'd like to do is ban the user immediately based on the words they post.

My forum is technical, so for example, if you post "Expedia" or "QuickBooks", the odds you are a spammer is nearly 100%.

If, when they type these keywords and submit the post, it would ban them completely and say something to the effect of "Based on the content of your post, you have been banned. If you believe this is in error, please contact support.", my life would be easier.

Alternatively, is there a way to achieve this already?

Thanks!

God bless.

James
