Literally search it up.. There is a queue which is used when Hypixel has a large amount of players online. Donators will get queue priority while nons do not.
Well thats complete BS bud...
I've looked on multiple pages of the Hypixel forums and you can bypass the queue simply by purchasing VIP or higher. (Or at least get higher priority!) https://hypixel.net/threads/queue.2867781/

+1 This is probably going to get turned away by whoever manages the plugins since sending requests to and from websites could open up new bugs to break MH, but as a dev this would be really cool to see!
Thats not P2W? Minecraft's TOS states that you cant give out in-game items for money (like diamonds, bedrock, etc). A server queue would have nothing to do with Mojang, so its not P2W.
