The metagame police always get way more annoying than actual metagamers. I don't think it's unreasonable to assume that players would have learned basic lore about common monsters from other adventurers or share basic non-secret information between scenes. Like, don't you have anything better to do than constantly pumping the brakes to point out one of the PCs stepped was outside the camp when a conversation happened or insist we RP not knowing what a troll is?

Online play is like the equivalent of how public events at the LGS attract all the gross troll-creatures who couldn't find a prviate group but with the entire internet as your pool of players.
