Are there any laws Against Gaming Servers abusing Donators?

Implaying on a minecraft server that i donated to and i got banned because the owner does not like me. I follow all rules on the server. Is this allowed or are there certain laws or guideline that could get this server in trouble.

Let the buyer (or donor) beware.

No, it's a private business. Unless there are rules against it in the Minecraft terms and conditions, there won't be any consequences.

Come play on my server man, my staff treat donators like royalty! I have factions, guns, /fly for voters, sky wars (over 100 maps), skyblock (custom challenges), creative (100X100 plots with end and nether too), kit-pvp with free and donor kits. I would love to have as many good players as possible! My in game name is JefferyMonfort AKA Gangsta_Jeff My servers are mc.craftpimp.com and mc.skywarz.net Come see the new revolution in minecraft!
