If we consider just the posting gap or the posting style of this guy, then this account seems to have been hacked twice. One should have been in 2017 and other one is 2019.
Going by his post history, the original Luno account seems to be an old miner from 2011. He should have started mining btc at the end of 2011 when the price was around $4/coin. He went offline on 2014. All of a sudden the account became active in 2017 and enrolled in a signature campaign for a payrate of 0.0003/post and started spamming with his bullshit one-liners. Spamming continued until the account was further hacked for the second time after 4 months. After a gap of 2 years, a scammer took over the account and started scamming poor newbies.
P.S The original Luno has received 144.86189425 BTC till now and probably would be a millionaire by now. He won't scam others for $75
