    Block the IP addresses that are being used to attack your server. They're all minecraft proxies. In addition to that, ban all of the individual usernames that are being used as they are all compromised accounts. If you want the easy way out, a simple IP ban plugin will suffice, but if you want to shield your MC server entirely you can go to the IP routing tables for your router and ban the IP addresses from even getting to the box that your server is on.

    They are all IP banned. But they are able to change IP's. Its professional hosted so I can't do very much to stop them.

    There's only so many IP addresses that they can get their hands on. Sort the IP addresses by hand and look for patterns, such as common subnets 123.456.*.* and ban them if necessary.
