People who rise to the bait of trash talkers need to learn to "man up" or learn to use the ignore button... or even stranger than all of those people could choose to avoid... (I better talk quietly as its a secret) going in to Plaza 2 what is purely there for PVP in this game ATM. There is no reason to go P2 outside of PVPing or 1 faction epic I think needs you to see someone there.
Surely if the argument is negative SL means you are betraying your faction (as you only get -SL from killing people allied to your faction) and this means cops will shoot you, GRs don't work and nor to apartment lifts. The why do the cops shoot you? the cops are bots made by City Admin, surely they should like in NC2 shoot anti city factions. Why shouldn't the lifts work? who runs the lifts and somehow stops you from using them. Same with the GRs, who owns them, who is stopping people from hacking the controls.
The negatives from having -SL should be that your faction and allied factions should be annoyed with you and somehow punishing you in some way, as that is the reason you are at -SL. So unless its your faction giving up your details to the NCPD saying "We need to have a talk with this guy, arrest him so we can try to get him under control." But why would TG say that to them...
