This is what I got from my host:

Our administration team is monitoring network 24/7 and we block external addresses if we detect abusive activity however if someone is overloading your site using some script from your side which generates too many SQL queries it can be very hard to detect because that address does not generate too much traffic. We recommend rechecking your scripts to prevent that from your side. Our administration team told us that it is possible that someone is abusing your application if the problem occurs at exact same time every day but we don't have any evidence of that, please check your HTTP connection logs available inside /logs/ folder in your hosting plan. You can add any address to deny list in .htaccess file, here are some examples:
http://www.htaccess-guide.com/deny-v...by-ip-address/

I added this to my root directory of the forum:

order allow,deny
deny from 213.186.12.
deny from 180.76.6.
allow from all

Do you think that this is the solution or a possible solution?

Thanks
