Last week I received 12,500 free mercury tokens in my Waves wallet. The message said something about them being distributed by darcr.us, which is the site of DARCRUS (DAR).
Looking into it it seems they are going to airdrop a lot more on holders of DAR:

Looks like an interesting option, what do you think?
