How To Test Your Dansguardian, Safesquid, POESIA, Parental Internet Filter Or We-Blocker Keyword Filter Anytime Anywhere

Keyword filters block unwanted web pages on the basis of potentially fallen words found in them. However, to be sure that a page is indeed offensive, keyword filters nowadays are not designed to block sites on the basis of just about any potentially offensive word. Instead they measure the number of potentially offensive phrases and often the number of times they occur so as to allow a limited number of occurrences in pages such as those on anatomy, forms requiring gender information, crime reports, statistical reports, administrative information, art etc. The leading keyword blockers like Dansguardian which is extremely popular on Linux or SafeSquid which is popular on Linux and Windows use this method known as a weighed keyword score.

By default, BlockHosts supports services that use TCP_WRAPPERS, such as SSH, i.e. services, that use /etc/hosts.allow or /etc/hosts.deny, but it can also block other services using iproute or iptables.
