Kinda obvious OP. Nobody think LFR isn't raiding, because even bleeding-edge raiders abuse LFR as part of progression.
People who say LFR isn't raiding are the same people who pretend anything that isn't bleeding-edge endgame isn't content, and will defend whatever arbitrary difficulty slider that separates them from the masses.
Their opinion is worth nothing, and are more likely to regurgitate whatever e-celeb twitch-heroes project onto them, even if that person was caught cheating. They'll take sloppy seconds as long as it puts them on a pedestal above someone else.
Back before paid transfers if you were caught abusing master looter or guild hopping you were blacklisted. If you were caught exploiting or cheating you got immediate action taken against you. All toxic behavior perpetuated because Blizzard back-seat enforcing their own game so they can rake in the money now and banwave later in a vicious cycle.
What next? LFD not dungeoning because Mythic dungeons exist?
