You're asking a difficult question right here, albeit I could say that it is a good one. Basically, if you take a look at the speculation section for example you will encounter a lot of people that are really desperate for money (the altcoin section is worse, i.e. people that hope for another 'rise' similar to the one with Bitcoin). I can't give you an exact answer, but in any case you should not make a faulty generalization.
You stumbled into signature spam hell, where people with poor English post similar topics to post in.
It has become horrible indeed. However, there are still some people that are signature campaign participants and make genuine posts.
