It's more likely newbies don't even know about that method to begin with.
Although depending how new the person is, I wouldn't recommend it to them as it burns through a fair amount of seeds/elixirs and it doesn't provide those resources back as you're not getting much tickets with this method. While gem gacha does exist, spending 100k a day for some seeds/elixirs as a new player is unlikely. I think the one who originally asked about raid events that started the discussion only started a week ago?
