Used this plugin back in 2019 (review below). Still works amazingly. The developer is adding more to recently. The features he's added improved the overall plugin. Get this for easy raid protection on your server.

Works really well! I asked for a suggestion or two on the suggest page of this plugin... And I guess it works with 1.12.2 servers, cause I didn't pay attention to the version until now, and it worked perfectly on my server, which is 1.12.2.

Best anti bot plugin my server was getting bot attacks and now it stopped cuz of this plugin i recommend this plugin for everyone :)
