Yes it is working perfectly fine because it is easier to find those people who are here for merit farming and here because they really want to learn about bitcoin and other alternate cryptocurrencies. I have found some people who are cheating although it is just a minor give and take merits but imagine if they have 5 - 10 alt account and placed in just one signature campaign. Even if they are just members or full members they can still get a lot of $ out of one campaign.
