You can find the source of a lot of plugins for any purpose on github.
You cannot expect any developer to be able to code everything on their with no basis of reference. It's perfectly normal for a plugin developer to go through the code of existing plugins in order understand how they work. After that they may decide to make their own plugin and add other features to it as required. In development I believe that understanding how current processes work and then experimenting on your own to see what you can do with it is important and not to mention what makes it fun. Lol everytime you want something available to millions of people you don't go and make your own internet, you build upon the already existing structures.Find better ways for the same and maybe one day even create your own medium like the internet. I guess it's all about research and experimentation.
In conclusion I think we can say it doesn't really matter whether the plugins were custom coded or not. If they were built off other plugins/got straight up from spigot. What's important is that it gets the job done, as developer you have to always look for bugs,better ways to get things done in general to make it easier for the users to interact or as the case is here: for players to be able to play smoothly. That is a difficult task. Also no decent server would ever give you the list of plugins it uses, a word of advice here if you're going to open a server of your own, do some researching and experimenting on your own to see what really fits your needs. There would not be any point in copying it off some other server, since all you're going to create is a worse duplication of the server.
