Whether being a jerk justifies banning I can't say - but his assertion that HN is biased has little justification (particularly when you consider that the writer himself is biased.) Kindly ignore.
It kinda comes down to what sort of "thing" HN is supposed to be -- whether it has a place for people like him -- but regardless, he's certainly not exactly hurting over his inability to play in our little sandbox here.
He's been a major drain/drag on the Node.js community, and makes the IRC channel a toxic wasteland for a good part of the day.
He trolls other sites as well... http://www.youtube.com/watch?v=IrkDqh9ZVog
I find his hook.io project (http://hook.io/about.html) particularly interesting, and the BDD testing app he was building for Node Knockout has a lot of potential as well.
Knowledgeable he may be, but professional he is most certainly not.
Edit: I must admit, however, that I'm interested as to why he was banned. I don't believe he's said/done anything spiteful and mean in HN itself.
Marak comes across as someone who's seen that and intends to emulate it, without the actual development skill or talent to back it up.
It doesn't happen too often, however. The community here usually has pretty high commenting standards, and there's peer pressure that encourages good behavior.
They of course aren't notified at all, so they're quite happy to keep adding comments to the site, all of which stay at 1 point and never get replied to (or even read by anyone except those with showdead on).
Since there's no messaging system on this site, if they haven't bothered to add any contact information to their userpage then there's no way to let them know.
I occasionally see these folks posting some pretty thoughtful comments while auto-dead, too.
However, this has been a subject of discussion here a few times, and nothing has changed; I don't expect it to.
I do expect that this site will be banned soon too.
I'm not saying that that's the best solution. A mefi-like $5 cost to join might be better, but then a) PG has to implement the payment stuff, and b) some people will complain about us charging nontrolls to get accounts.
It's possible that there could be some system where if, say, 5 people with at least 200 karma will vouch for you, it's free, but then there's even more complicated code that needs to get written, and people will complain that you can only join HN if you pay or are part of the "in crowd" that know lots of HNers.
I actually think that could work really well though. If for the first month/50 karma, those people were supposed to moderate the sponsorees comments and give them feedback on what they're doing well and what they're doing badly, we might have a lot fewer complaints about all those noobs that are ruining our site.
the article you clicked on was most certainly not submitted by nodejitsu.
news.ycombinator has a long history of squashing articles and submitters that aren't funded by y-comb.
most of this is done through their "silent" banning and censoring mechanisms, that leave people not even realizing they have been silenced.
i hope you enjoy this article, and remember that HN is extremely biased and that you should keep your horizons broad."
While I would agree that HN is bias towards YC-funded projects I would not agree that it is biased against non-YC projects or news. In fact, the majority of the items on HN are non-YC. This also follows for submitters and commenters for the year or more I've been here.
On a different note. Hpricot is not representative of Ruby scraping anymore - nokogiri (http://nokogiri.org/) is where it's at. Which has a Hpricot translation layer if you need to change. Even when I decided to solidify on Python for everything else I will still go back to Ruby just for nokogiri when it comes to scraping.
