My site does not yet use W3T, but we will soon. We have a problem, as I know many sites do, with a few nutcases who live to post junk, antagonize, flame, vandalise, etc. We've been suffering with some of the same obsessive lunatics for months.
We don't have a register-to-post system, but registration won't help much, since it's no big deal to conjure up dozens of email addresses (I know W3T can reject accounts from hotmail, yahoomail, etc, but there's always a way).
Other than logging IP addresses (which is of limited usefulness), what other security stuff is built into W3T?
Does it log browser info? That's critical...more information helps!
Can admins call up listings of all new registrants over a given time period, complete with IP and browser info, in order to spot newly banned users immediately resigning up from a different ISP (and thus help learn their ISP and browser range for more effective future blocking) or from a new dial-up session with, say AOL (to learn that user's range of dynamic IP prefixes)?
Can admins call up a record of all actions (not postings...actions!) by any one registrant over time so we can spot behavioral patterns of known offenders? (that, in the end, is the only really effective way to block a psycho; spot their site-navigation habits and tendencies).
What else can W3T do to help with obsessive serial problem posters?
If any of those things are NOT in the program, then let's call this a feature request!
