plugin license
 

I have a plugin that I don't want to be used by everyone (the plugin is not mine, but I updated the plugin quite a lot and added a lot of things to it.) How can I add a license or something similar to this plugin or a code may be required for the plugin to work.

you must read amxmodx license before doing this.

It is very easy to bypass most, if not all, implementations of things like this so it is mostly useless. Also, it is not legal to distrubute a compiled plugin without the source code (this is part of the license).
