Definitely there are some members that received the merit airdrop, some are bounty hunters and never had more merits again. Such people can be poor posters.
Some received the airdrop, sell their accounts (and probably they have many). Who supposed to be a newbie bought it. I regard those and some other bounty hunters as newbie legendaries.
Can we conclude that not all legendaries are knowledgeable in the forum? I myself was scared to answer or quote legendaries when I initially joined the forum.
Yes.
