I'd assume at this point that they aren't. Their site isn't updated, they haven't marketed or anything in a LONG time, etc. I haven't even heard anyone ask about them in years.
Exactly this. I checked their social media accounts - last facebook update has been done on Coinlearn May 25, 2014, last tweet message was sent in 2015.
Also, there is no proof of payment newer than from 2015. So it is safe to assume that at this point their site is pretty much abandoned.
To avoid disappointment please don't expect any payment from CoinLearn.org
