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...
