Running certain plugins will cause your server to be blacklisted
Valve recently announced they would blacklist any servers running plugins that are offering to their players false inventories and/or profiles as a free or paid service. Essentially this refers to the so-called !knife and !ws plugins and the popular weapon paints plugins.
In order to comply with Valve’s wishes, we ask all of our users to remove any plugins of this type, as running these plugins will cause your server to be blacklisted. We’ll also be actively purging these plugins from servers running with us.
Running a plugin of this type will cause us to immediately delete your server with no refunds offered, as you run the risk of blacklisting your server and any other servers running on the same machine.
