RSS[TF2/Any?] UGC Blocker

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

sm_ugc_scan_uploads "*3"
Performa a scan for Trojan:BAT/Killav.B in sprays and jingles.
If a file scans positive, all admins with the kick flag will be notified and the player will be banned (using sourcebans++ if applicable).
Please validate the file & ban manually as the automated process might not work 100%.

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.
  • FileNetMessage
  • LateDL
