Topping the app store with viral loops

Owenwil, I am curious to know why you consider these are spammy tactics. Do you consider the tactics used by Dropbox where users were given free space for sharing with friends as spammy? do you also consider sharing something which is valuable to your friend as spammy?

I think it is only spammy if the app misleads the users and sends out messages on their behalf without them knowing. If everything is done in a very transparent manner then I don't think it is spammy at all.

I would be surprised if many people would agree with you.

Candy Crush, Dropbox and 4 pics 1 word are three incredibly well thought of applications which have provided entertainment and practicality (in Dropbox's case) to millions of people around the world.

So, saying they are 'some of the worst' applications on the iOS App Store couldn't really be further from the truth. In fact, many would argue these are three of the best applications app consumers have ever seen.
