Hi Gurus,
since few weeks i`m trying to stop one spam robot on my forum. It all the time spamming my forum. 0-40 spam posts per week.
I have installed everything what is possible in my CMS *captachas, filters etc.etc.. Most probably this robot using TOR network to spam websites like mine. Its changing dynamicly IP but the published content is in 70% the same.
Is it possible to filter http request body, find some words "viagra,pills,penis etc.etc." and display 403 ?
How to filter all incoming reqeusts to my application ?
Lets say I have a car forum and I would like to block all robots/persons trying to publish everything what is possible about flowers.
Can I do this with NGINX ?
How to block spam with NGINX ?
