Minehut used to be good. They ruined it.
Minehut has gone in only 2 years from probably the best free server hosting company to the worst. Free servers were what this whole company was based around, however they limit the total playtime and force you to pay them money to be able to play on the server. You have to pay to download your world, you have to pay to do practically anything besides play and start the server. The only good experiences I had with Minehut is when they were a small and wholesome company and didn't put an ad in your way before you do any activity on your server. Just don't ever use it. You are far better off using an actually decent free host like Aternos or running a server yourself.
