Another day, another high SV.
This from what I can see is a player exploit somehow, I have done some research on what the source could be. Looking back at previous bans, we had someone on the server giving similar threats to what is happening and their steam name at the time linked to a exploit that looks to be hex code so presume this is another form of injection cheat into CS:GO. I have attached the screenshot that was on the shop page, the page has since been terminated from the site so cannot provide much more information unfortunately(Seems to have been removed over night).
I shall keep updating until we come to a conclusion on a fix. I have my hosting checking for any signs of an attack so will feed this back once I know.
