Actually, the original post was submitted. As was pointed out above, this is not blogspam. It's a result of HN's policy that only original titles can be used. The original blog post has a title that isn't nearly as friendly to upvoting. It's a system that has its pros and cons, but it's what HN has decided to do.
Well, boingboing is festooned with ads and affiliate links. It's a business, after all.
The problem is not so much whether BB is blogspam[0] but that blogspam often has a better chance of getting up-voted on HN.
[0]: My view: There are many ads, but half the time there's some sensible additional commentary for the target post, so there's plausible value in exchange for the ads.
True. I've found many good and useful things there, but every so often they post something that is clearly dubious or a hoax. That's fine as things go; people make mistakes.
But when caught out they tend (to the extent I've seen) to either say nothing or to just delete the post, rather than make an effort to correct mistakes.
(On a related note, I'm amazed at the level of snark and bile in the some of the comments on Boing-boing; the nasty ones rival or out-do the worst of Youtube.)
