UGC Blocker
User Generated Content (UGC) can become a concern for server owners if bad actors decide to show up.
This can include bad language in chat, on items names and item descriptions as well has NSFW / illegal imagery for custom decals and sprays.
While this plugin was originally written for TF2, I hope I changed it enough so it should work for other games as well.
Features- Restrict usage of sprays, jingles (TF2: decals, item names and descriptions) based on TrustFactor
- Log files uploaded from clients
- Scan uploaded files for fake AV triggers (and ban on detection)
- Ingame commands to forward and backwards look-up of filenames for a players spray/jingle
- Late download sprays if initially blocked due to permission granted later
Config
This plugin allows you to control when players are able to use custom decals, item names, descriptions and sprays through the following convars.
sm_ugc_disable_decal "0"
Always block items with custom decals
sm_ugc_disable_description "0"
Always block items with custom descriptions
sm_ugc_disable_name "0"
Always block items with custom names
sm_ugc_disable_spray "0"
Always block players from using sprays
sm_ugc_disable_jingle "0"
Always block players from using jingles ('sound sprays')
sm_ugc_trust_decal "*3"
TrustFlags required to allow items with custom decals, empty to always allow
sm_ugc_trust_description "*3"
TrustFlags required to allow items with custom descriptions, empty to always allow
sm_ugc_trust_name "*3"
TrustFlags required to allow items with custom names, empty to always allow
sm_ugc_trust_spray "*3"
TrustFlags required to allow sprays, empty to always allow
sm_ugc_trust_jingle "*3"
TrustFlags required to allow jingles, empty to always allow
sm_ugc_log_uploads "*3"
Log all client file uploads to
user_custom_received.log
Some malicious spray files were used to trip false positives in client anti-virus
Spray Exploit Fixer catches this and I recommend you use that plugin.
Items that do not pass the filters will currently just be removed from the player.
In case of weapons i might look into using TF2 Gimme or TF2 Items to generate and re-equip "clean" versions.
User custom files will still upload to the server, but the download is limited:
If a client connects while a spray or jingle is blocked, that file should no longer download to other clients.
In case sprays or jingles get blocked after they join, no new clients will receive the files, and the action should
be blocked from being executed.
Getting permission to use sprays or jingles after being in the server for some seconds will
not send the files
to other clients. The player should reconnect in this case to trigger the download.
Commands
The logs can also be checked directly from the server with the command
sm_ugclookup or
sm_ugclookuplogs.
Both commands require the Kick flag by default and the former tried to check online players first.
Arguments is a player name, SteamID or a filename. If an online player is found, it will return their current
spray and jingle file as well as the types of UGC they can currently use. Otherwise the log will be scanned through
and the last up to 50 entries will be dumped to your console, including the timestamp.
The command
sm_ugcscanusercustom requires the root admin flag and will scan all files in
/download/user_custom
for suspicious content, as if just uploaded. Depending on how often you clean that directory, this might take some
time. This command will not ban players, but it will still report any files it found.
Dependencies
Dependencies that do not apply to your game should only be required for compilation.
- This plugin requires TF2 Attributes to check if an items has a custom name/description/decal.
I'm using nosoops fork, but FlamingSarges original might work as well. In any case Version 1.3.2 or above is required.
- TrustFactor is required to check players trustworthiness.
- For late downloading / invisible spray fix install one of these (optional). While FNM is more geared towards single player transfers, both
plugins seem fit for the job, and should work. Without this, it might take a map change after another player joins before they receive that
players spray/jingle file.
