You need to buy the game on Steam

You are not real

No, that will not get you banned. Read the anticheat policy https://plutonium.pw/docs/anticheat/

It seems you did not uninstall the entire mod.
You should be more careful when installing mods. Having a list of files you installed would have saved you all of this trouble.
You should find where you downloaded this mod from, then see the list of files you would have downloaded when installing it, and then try deleting those.
If that does not work, since we can't tell you what you did, it's best if you start fresh by reinstalling Plutonium. I hope you did not put anything in your game folder because that can complicate things.

It would be best if you asked individual server owners that question. VPNs are usually forbidden to prevent people from evading bans. Please understand that Plutonium hosts zero servers and all you see on the server list are community servers hosted by others. They can set whatever rules they want about VPNs.

Stop asking how to pirate on our forums, thank you.

DJseanyB You take this a little bit and of that and boom you get a watermark, you are not going to do social reverse engineering on us, sorry!

A workaround should be deployed soon from what I heard, the limit should appear as if it's actually 30 again.
If not, be patient as it might require a system restart for the fix to apply on our end.

I believe the conversation got sidetracked and now we are discussing a different topic from what you originally wrote in your post.

FragsAreUs mentioned that you can't get banned for using a VPN when logging in with the launcher, which is completely accurate. Additionally, having cracked game files will not result in a ban, so that comment is confusing.

Please refer to our anti-cheat policy here: https://plutonium.pw/docs/anticheat/

If individual servers kick you for using a VPN, consider turning it off.

Please, search for this error message. You will find many threads that cover the same issue which have already many replies.
You CANNOT do anything, the server needs to be restarted. Join another server.

it's hard to diagnose issues like this because it could be caused by a variety of things.

Please consider hosting a normal dedicated server for you and your friends which will act exactly like in a private match. You can password-protect it so only your friends can join it.

Small correction, I looked at your case and this was the second ban placed on your account, sucks to be forgetful. Unfortunately, as the policy says, you cannot play on Plutonium anymore. Thanks for your time with us.

You know you could have just read the AC policy, right? https://plutonium.pw/docs/anticheat/
It is not really about forgetting to enable LAN mode which would have got you a 7-day ban, but the bit where it says that if you attempt to bypass you will get an extended ban, it seems you tried a bunch of times to get around it causing the 30 thousands days ban time.
