Using a browser to piss off IRC users, or, spamming #redditdowntime 27 Jan 2010
miscellaneous software development

One of my most favorite sites on the internet, reddit, took some downtime this evening while doing some infrastructure (both hardware and software) upgrades. On their down-page, the reddit team invited everybody to join the #redditdowntime channel on the Freenode network, ostensibly to help users pass the time waiting for their pics and IAMAs to come back online.

Shortly after reddit started their scheduled outage, I joined the channel to pass the time while I debated what I should do with my evening. Within minutes the channel was flooded with a number of users, varying between spouting reddit memes in caps. link-spamming or engaging in casual chit-chat. I complained to one of the ops and fairly well-known-to-redditors employee: jedberg about the lack of moderation and he nearly instantly gave me +o (ops) in the channel. Not one to take my ops duty lightly, I started kicking spammers, warning habitual caps-lock users and tried to keep things generally civil through the deluge of messages consuming the channel.

Towards the end of the scheduled outage, some automated link-spamming started to appear and once it started it triggered more and more link-spamming. Clearly whatever was behind the bit.ly link was responsible for the self-propagating nature of the spamming. While the other moderators and myself tried to keep up with banning people I used wget to fetch the destination of the clearly malicious bit.ly URL to determine what we were dealing with. What I found is one of the more clever bits of JavaScript I think I’ve seen in recent months.

After bringing the site back up for a few minutes, reddit had to take it back down after noticing some problems with the upgrade, so another flood of users filled into the #redditdowntime channel and the link-spamming got worse. The most interesting aspect of the JavaScript in the code snippet below is how simple it is, I’ve commented it up a bit to help explain what’s actually going on:

DIGG ROOLZ! REDDIT DROOLZ!
