Ask HN: Is Phonebloks Using Next Generation Copyright/Patent Trolling?

Phonebloks (http://www.davehakkens.nl/) is an ideadeck web page making the rounds today. It appears to be a page made by a designer pitching a product to nobody in particular. The person has no interest or ability to make the device, they just want people to 'like' it in hopes it gets made.

This is the second such website I've come across this week after trying to see if a tchotchke from 'Doctor Who' was available for sale. It wasn't, but some guy posted up details about how he wished someone would make one and any interested companies should contact him.

If a person or company ran with the idea are they somehow responsible for compensating the people who post things like this? Is this a new form of poor man's copyright or lawsuit trolling?

I'm worried because if I had an idea, I'd research it first. If I came across some website that had the same idea I think I would give pause to developing it further because of this.
