If I am not mistaken, ESteem didn't do any airdrop. I mainly use ESteem Surfer when I'm on desktop so I was able to accumulate some ESTM tokens. XD

I highly suggest you also use it as it's quite easy to get those sweet ESTM's. Every comment you make gives you 5 ESTM and 0.3 ESTM for every upvote. If one is very active, I think they are able to get a decent amount of ESTM daily. XD
