I quickly made this plugin to handle the apparent new exploit that allows players to join and stay on a server with a pending steamid. A pending steamid means that the server hasn't finished validating the player's steamid. The exploit takes advantage of this and their steamid never
validates. This can make banning them more annoying and any scripts that ban solely by steamid will be confused by them.
The plugin works around this by kicking clients that go active (spawn) with a pending steamid. 99.9% of the time a player's steamid will be validated before they spawn.
Here's the only interesting bit of code from the plugin:
void CServerPluginPending_ClientActive(edict_t *entity, bool bLoadGame)
int userid = g_Engine->GetPlayerUserId(entity);
if (userid < 1)
const char *steamid = g_Engine->GetPlayerNetworkIDString(entity);
if (!steamid || !Q_stristr(steamid, "PENDING"))
/* "kickid " = 7, kick message = 40, \0 = 1, + 1 for int length thing */
int length = ((int) log10((float) userid)) + 49;
char *command = (char *) malloc(length);
Q_snprintf(command, length, "kickid %d Network ID didn't validate. Reconnect.\n", userid);
Oh, and it's for SourceMM, of course. Linux binary, Windows binary and source code are in the attached archive. Everything is public domain. The Linux binary does not require libstdc++ whatsoever. Just shove the file in mod/addons/ and run "meta load addons/pending_mm".
