3074 is now permanently deprecated and its legacy is now moved to Final Solution.
You can download Final Solution at Vault of Glass.
Netlimiting at any condition for any purpose is bannable. USE AT YOUR OWN RISKS!
The installation steps are similar to 3074, if you want more details you can visit the Manual in Chinese.
Before you report any issues, please check your version, to make sure you are using the latest build and using compatible NetLimiter version (for now, FS is tested with NL v5.2.6.0). And you should report with these information.
BUT YOU SHOULD BE AWARE THAT I don't guarantee that these things is going to be fixed/implemented/changed.
