Hi Niels, I am sorry to hear you`re having problems with trolls and I can perfectly understand how annoying, disruptive and possibly costly that might be. However, I would not encourage IP filtering based solutions to handle SPAM in general, simply due to the scarce nature of IPv4 addresses (and the resulting high number of possible false positives). When IPv6 will be popular, maybe that will become a viable solution. So yes, I`d also suggest that you try an e-mail based filtering system (since there seem to be databases with problematic e-mails) where individuals can be pinpointed and flagged as spammers. My 2 cents, Eduard On Sun, Jun 10, 2012 at 12:16 AM, Niels Mayer <nielsmayer@gmail.com> wrote:
This is either a feature request or a request for discussing solutions to the issue of known comment spammers against XWiki installs.
There's known spammers like davycrokkett@hotmail.com (see http://www.nielsmayer.com/bin/view/XWiki/DavyCrokkett ) which have to be managed and curtailed for any XWiki install enabling comments.
During registration, it would it be nice to check sites like http://www.stopforumspam.com/ and prevent registration emails from going out to known comment spammers.
For example, the aforementioned spammer is listed at http://www.stopforumspam.com/ipcheck/111.243.227.227 suggesting Current country of origin: Taiwan, Province of China

It would also be interesting for such flagged users to return a list of associated IP's (such as above) which could be blacklisted as well.
I guess the correct solution would be to use http://extensions.xwiki.org/xwiki/bin/view/Extension/Social+Login but then the spammers would just end up getting twitter, facebook or foursquare logins and use those instead of hotmail accounts.
