The IP this site is hosted on is quite often on an IP blocklist for compromised sites. I can work around this but there may be users trying to get to the site that can’t and don’t know why. They may just assume it doesn’t work.
I guess the site host is also shared with other compromised sites or sites used to host spam, spyware, viruses or other junk. My firewall blocks my access to the forum 95% of the time due to the blocklist. Right now the forum IP address is currently on a FireHol Level 3 list.
