A bit of a tangent here, but just today I've come across a reason why the current dust limit could be a good thing. I'm guessing this is a bot, because I'm pretty sure you can't manually post every 5 minutes, but @adsofficial18 seems to be earning something from it. Most of the posts are only getting the odd cent from @cheetah though.
This also gives a case for limiting daily blog posts. Do you think HF20 would have any effect on discouraging this sort of behaviour?

I reported it. I forgot about bandwidth limit. I'm surprised they managed the amount of posts they did before it ran out!
