cryptocurrency airdrops and the joy of registration

Whilst browsing through steemit and other media there is no day when you dont see something about another airdrop. I mean ok, projects have to get peoples attention and the more projects we have the more difficult it is to get peoples attention because they just cannot see the forest because of the many trees they see (I hope I got this translated so you can understand whan I mean).

You can ignore them if you want... But wait... You can get something for free? That is too tempting.
But think about for a second. It is not for free! You have to register here and there, post on blogs, make videos, give them your data. A lot of work for some tokens that could be worth something or not. :)

Just my thoughts.
