Don't think that there are people looking for more complex campaigns to participate and skip easy ones. The greatest profit of this action is to force people learn more about the project, get deeper into it and bring friends. But not many want to look for some information in order to get extra money, they'll preferably do RT, tag friends and wait without any knowledge what coin will they get in case of winning.
Of course, the number of users who don't want to do anything simpler is quite large. This is disappointing, because such companies are a rather rare and valuable opportunity, which also brings profit.
