Not true at all. Prplz (Kohi's owner) and Simon (Hypixel's owner) all said that their ranked gamemodes increased the number of closet hackers, that's the important thing, closet, not blatant. We all know that one client (starts with a V) I won't mention it's name as I don't want to promote it, however, this client add very little change that are hard for an AC to detect them. For example it could delay Knockback, therefore they are able to get more hits, it looks like lag. As many people know the multiplayer reach is 3 blocks this client increases it to 3.1, therefore it's impossible to detect and they have an extreme advantage over you.
