Thank you all very much for your answers.
At the time of writing this, it didn't work on my server. What I've tried so far:
- putting sm_cvar mp_tagging_scale "0" in server.cfg
- putting sm_cvar mp_tagging_scale "0" in gamemode_competitive_server.cfg
- putting sm_cvar mp_tagging_scale "0" in sourcemod/sourcemod.cfg
- putting mp_tagging_scale "0" in sourcemod/sourcemod.cfg
- directly typing sm_cvar mp_tagging_scale "0". Replies with [SM] Changed cvar "mp_tagging_scale" to "0" but does not actually remove tagging
