I often see a lot of them especially in the Alts Section and Bitcoin Discussion, it's obvious that they are just posting for their bounties . Some reply with the most common answer where everyone knows and it seems that they are just repeating it. Maybe it should be added as one of the things to report to the moderators (I think its from welsh thread)
Is it possible to create a kind of rule of the thumb in reporting e.g. if someone creates a topic in Bitcoin Discussion when there's a really similar topic that has been opened (and discussed and had the proper answer) in a months time (or later on in a few months time) then the topic should be reported to be locked and OP has to be pointed to the old topic, to check it for the answer? (My favourite is: Bitcoin is better than gold/cash/etc... and similar ones...)
I know that for the most of the people it's always easier to ask and not to search for something, but we should stop it somehow and let people start searching (on the site, or use google.)
