Block Postings Based on Content or IP Address

Everytime someone attempts to edit a page, PmWiki scans the Main.Blocklist ? page looking for strings of the form block:something where something is a sequence of characters to be excluded from posting.  Thus, block:spam.com would prevent any edits containing "spam.com".

In addition, the Main.Blocklist ? page can contain IP addresses or ranges of the form a.b.c.d or a.b.c.*; any postings from a listed address are also blocked.

In general the administrator will also want to edit-protect the Main.Blocklist ? page to prevent arbitrary additions/deletions from the blocklist (see PmWiki.Passwords).  It's also possible to read-protect the Main.Blocklist ? page so that others do not know the exact phrases and/or IP addresses that are being blocked.
