Is it because you decompiled the sprunked FV demo and got a screen saying he has your IP and general location and he may use those to find out where you live and can threaten to publish the info on-stream so that you never leak his mods ever again and he might do something WORSE than that?
Oh... So the reason is he sent a link to an ip-grabbing website causing him to get your IP and geolocation which can be used to get public exposure threatens according to RanDUMB in a fanmade doc?
