No, the server is hosted by MCProHosting.com and uses a MCPC+.jar [Custom server Jar] (Server that implements both Forge, and Bukkit. Mods and Plugins). That helps make Pixelmon (A Mod that is made for Minecraft Forge clients) work for multiplayer. And makes use of bukkit plugins for security, protection, and foundation. For the mods implemented.
As far as illegal standards go if you don't have a legit minecraft user account with Forge installed as well as pixelmon. As well as a positive record on MCbans.com you can't get in...sorry for the inconvenience.
