Wow, what a spam storm! I rolled back all those changes and locked the wiki for the moment. There’s no fighting a bot manually.
I’ll look into what allowed this to happen later today and hopefully enable page editing and commenting again.
Update: IP number blocked, lock removed. That was weird.
Wow, spammers are learning about role playing games…
I still hate spammers, of course. But I have to confess, an adventure “on the most dangerous island of the world, R’lyeh, the resting place of the great old one, Cthulhu.” Just, wow! Or woe, I guess.
I’ve started to note a particularly nasty kind of spam for the Best Essays website. They don’t only add links to the wiki pages. At first they posted entire new pages that are on the topic of writing essays to CommunityWiki. But lately they’ve been using my username (!) to make edits. I assume they’re trying to sidestep peer review. I’ve just silently rolled back any changes they made, but today I saw another edit using my username, and when I investigated I found how they had experimented with the rollback function themselves and linked to an old revision containing a spam link to Best Term Papers. There must be real humans at work.
Here I am trying to send mail using some Perl module. But most of them seem to be written for the last millenium. They work best with a local SMTP host. For my own needs, that no longer works. The webhost doesn’t have a sendmail binary available. The SMTP hosts I can reach require SSL and TLS authentication. Now I’m slowly digging into MIME::Entity, Mail::Internet, Mail::Mailer, Net::SMTP, Net::SMTP::SSL, Net::SMTP::TLS…
After experimenting with the four or five mail accounts I have access to, I was finally able to get the following to work:
my $from = 'firstname.lastname@example.org'; my $to = $from; my $host = 'mail.epfarms.org'; my $user = 'alex'; my $password = '*secret*'; use MIME::Entity; my $mail = new MIME::Entity->build(To => $to, From => $from, Subject => 'test', Path => '/Users/alex/test.html', Type => 'text/html'); use Net::SMTP::TLS; my $smtp = Net::SMTP::TLS->new($host, User => $user, Password => $password, Debug => 1); $smtp->mail($from); # sender $smtp->to($to); # recipient $smtp->data; $smtp->datasend($mail->stringify); $smtp->dataend; $smtp->quit;
Often I log on to my various instant messaging networks (→ Contact) and some dummy Yahoo account will send me spam. Something like the following:
Back at work… got over 10’000 spam emails in my Junk folder, and about 300 mails in my Inbox with a 50:50 mix of spam to ham. Not too shabbby and lots better than in previous years!
I switched to GMail a long time ago because I felt that GMail had superior anti spam measures in place. These days I’m not so sure. I have less mail in my Spam box (4065 right now), and yet I have to manually mark about a dozen mails as spam every day. Are other users poisoning the spam filters? Maybe inactive accounts gathering spam negatively affect the filters…
Well, I’m being hit by spam of the form

How stupid is that?
Unfortunately, that means you’ll have to answer a question when you try to post to this site.
When an idiot comes along and spams twenty pages on my site, I can easily roll it back. But all changes are recorded for posterity in the log files, and therefore they appear on RecentChanges and thus also in the RSS feed. Too bad!
Unfortunatly simplistic schemes won’t work: I cannot skip all entries whose last edit was a rollback. I need to figure out what edits where undone by the rollback and then check whether there are any remaining edits in the current time window… Damn!
