Other Possible Exploit for Clockwork/Garrysmod

So, the server I co-own just had a nice visit of about five minges, today-

Yes, it didn't go well for them as they aren't so good at blending in. First one to join, inventory had 73 seperate scripts in it. "I found it in the sewers." He has <45 minutes of playtime. Second one, is a completely new user, spawns with a weapon. Third one announces, "Server lagging; oh." well before they began their strike-

My server console was spammed with this, caused immense lag.

Code:

Lua Error: [Stacker STool] lua/includes/extensions/net.lua:182: net.ReadType: Couldn't read type 69
1. error - [C]:-1
2. ReadType - lua/includes/extensions/net.lua:182 
3. ReadTable - lua/includes/extensions/net.lua:121 
4. func - lua/weapons/gmod_tool/stools/stacker.lua:451 
5. unknown - lua/includes/extensions/net.lua:32

Perhaps somebody can look at this, maybe find how it could be preventable in the future.

 

Try 'say no to exploits' on the gmod workshop. It patches a lot of exploits with addons.

 

Can you post the SteamIDs of these five individuals, please?
