I came back about 2-3 months ago, I think, and it's quite upsetting to have to see these posts.
So, we've got an IP leak, a DM leak, and a new "probation" punishment that's being beta-tested.
And the official admin response is, "Get a VPN."
I have to admit it, nowadays, a VPN is very strongly suggested, especially for Garry's Mod. It's an old engine game; there's not much of a solution to protect everyone.
As for any exploits that lead to such actions like doxxing, IP grabbers, and RATs, the only solution would be to fight them and investigate them if they affect the community. Be careful with what you share, and be careful with links and who you trust.
For the people who got their IP leaked, I strongly suggest, for your safety, that you contact your internet provider to reset/renew your IP. If you mention to the provider that it's related to a security breach, they will most likely do it free of charge.
