I t seems to me even extremely incredible that a person can easily and quickly navigate such a platform with so many requirements and rules, to make their first post well, to know where to do it, how to do it, what tags to use, without anyone helping them with it, saying: I found steem while researching altcoins on Binance. Doesn't sound plausible to me.

Yes, I agree. Even though I was introduced by a well-known Steemian here, Hira, I made a bunch of mistakes, rather blunders. I was thinking the same: how on earth is that person so well-versed with the rules? Then, they tried to lure in the support of well-known mentors. I must say, they played really well. But it was short-lived. Lol.

Unconditional support by all means from the beginning, often leads to the need to remove already given votes and unfollow people.

Agreed!
