If you have stayed up to 5years in this forum, you would have mastered where the mistake is from, for you not to rank up as expected of you. Were you less consistent in the forum posting back then around 2017?
Sure, 5 years is a long time to learn. So he knows and sees how the users here write, it should inspire him.
Having said that, you can't earn merit in this forum if you can't put effort into your posting. You start by being consistent in the forum, You posts when necessary, and expecting nothing in return. The mistake some users make is to be less active in the forum, and expect a miracle to happen.
But I also thought there might even be him having merit just for getting an airdrop. So that he was too satisfied and comfortable with it. So that he does not want to contribute usefully to the forum. There is no need to learn. Although I am actually also sure in this forum that there are many helper threads to obtain merit. But indeed if the quality of the post is not worth it then don't expect it. Perhaps the best advice is to maximize learning and expand the discussion in his local thread.
