Kailash Nadh is probably someone we’ll hear from more.
He’s 18, and author of the BoastMachine, a php/Mysql Blogging engine. The Boast machine is, though maybe a bit less sophisticated than WordPress, very nice and easy to install. It takes some ideas from bulletin boards: threaded comments, BBcode. Other projects of his are a news aggregator and a Pingoat, a Ping-o-matic clone.
Some time ago, he wrote a paper on spamblogs, that he’s apparently been putting into practice since: hence Splogspot, “The web’s only Spam search engine”, he announced yesterday. It’s a bit of a funny way to generate publicity for what should become a public blacklist of splog, accessible via an api you can check any url against (api doesn’t yet function apparently, see my comments at his blogpost). The database has been fed by the 1 million blog pings he has received so far for Pingoat, of which only about 6% passed through his filter.
An analogous (and, as far as I can judge, more advanced) project is Antisplog.net, featuring the simplest url-append api imaginable: this blog returns a 0 and is apparently not a spamblog. They’ve actively spidered about two million blogs to test the algorithm. Judging by this review (a test run of a sample of 42 spam and normal blogs) it works both fast and relatively accurate. To be continued!
