Is it actually easy to find a game without bots and hackers, or is it only on certain community servers?

Probably a bad idea. If you really wanted to do it, you should add plug-in support to your main project, then create a separate repo, maybe under a different account, with the potentially illegal yts download plug-in. That way only the plug-in repo would get DMCAed and could be mirrored by other people, or hosted off GitHub.
