Hi,
I submitted a report however to maybe speed things up I am also posting here.
Just bought a new dedicated server and moved a few sites to it.
It seems its ip/range was previously blacklisted by an offending domain by avast.
The domain currently being falsely blocked is: haruhichan.com
A large percentage of the site's userbase are avast users and the situation is infuriating them.
If you can please sort this situation out asap that would be great, many thanks
