What do you mean by someone bought you something? I'm guessing you got the "Buycraft" message when you entered the server?
It's possible you may have purchased the "TP back to spawn"? Or, something, doesn't always have to be a rank.
Maybe a clear inventory? As stated above, please provide more information so we can help with your problem.
Yes, on the Mineverse shop for free. It's generally used for getting rid of glitched items from your inventory.
Someone probably just sent you the TP back to spawn/Clear inventory package. If you still believe that it's a rank or something, go to Skyblock and see if you have any spawners and then go to Skywars to see if you have any Skybuck, they're the only things apart from ranks/capes which you can buy on the Mineverse store.
This has happened to me a few times as well, but I have not been TPd back to spawn, nor has my inventory been cleared. I'm not 100% sure what it is but don't worry about it, It's probably nothing.
