Thanks for all the answers!
I added the list to my htaccess @misterbit
And @gifted I currently have a similar script on my site
https://bitcointalk.org/index.php?topic=1211353.0However I can't get the last step to work
I can't find this <form method="POST" class="form-horizontal" role="form"> in my index. (I am using faucetbox btw.)
Do you know what I have to do there @Racey
So my current security only is the htaccess file with the deny from IP deny from IP ect..
and I use reCAPTCHA now.
However I don't think that this is enough (is it?)
and I want to try Cloudflare on my site but I have zero experience with it.
And faucet box says:
Be careful! This is an advanced feature. Don't use it unless you know what you're doing. If you set it wrong or you don't properly configure your proxy AND your server YOU MAY LOSE YOUR COINS!
So I am afraid to lose my bitcoins..
And I am definitley going to take a look at CSF firewall when I have the time.
Are there more things I can do to prefent bots from accessing/using my site?
