That being said, I don't think there's anything particularly wrong with accounts that exist specifically to submit a given site's content (even programmatically), since that content must be still democratically approved by the user base. I think vote-brigading is a much more serious issue, and one that HN seems to deal with well.
Why does it matter who does the submitting?
Dailydot, extremetech, pcmag, geek, macobserver, betabeat, itworld, bostinno etc have collectively operated dozens of acounts to spam their own stuff, none of which met an actual community member's standards for submitting a story.
Individuals submitting their own blog posts and especially with success are usually so low volume they're not even noticeable unless they overdo it and inevitably get called out for it.
I prefer to say "could" instead of "have" unless you have definite evidence.
Plus dailydot are just getting started with the OP + 'sexyalterego'.
At least I try to always make good submissions, and usually HN only let me submit twice every month...
When I joined HN I submitted a lot, but suddenly I could not submit for two weeks, then sometimes I can submit twice or three times in a week, and then have to wait two weeks again...
Plenty of people submit their own content. In fact, it's encouraged. You have reddit confused with digg, somehow.
Once, someone submitted one of my blog posts about a rather interesting bug in a AAA game to /r/programming. Over 1,000 net score. Out of curiosity, I submitted the same post myself to /r/games. -7 score.
> If over 10% of your submissions are your own site/content, you're almost certainly a spammer.

You could add a lot of value to the discussions and to the DailyDot if you were to participate to some extent in the discussions.

It's a shame the mods didn't shitlist your domain entirely, you're obviously here just to exploit HN.
But I will concede it could be some random, unaffiliated person who just really, really, really, really wishes we would get our news from dailydot!
That definitely sounds more likely than spam on the internet.
He's most definitely not Jay Hathaway, AKA sexyalterego on reddit, currently "assigning editor at the Daily Dot".

I for one am shocked it wasn't some random unaffiliated person who just really, really, really, really, really, really, really, really wanted us to get our news from dailydot.
I pointed this out once before, the last time they wrote an article and submitted it, and that was about the same thing too.
