Stop flaming these guys on the Forum, if you don't like it, deal ingame with it.
When we started the IAF|back in the day (Yes, unofficial IMG faction, with a similar purpose) people went ZOMG!!1!! NO U CAN'T HAZ CAPSH!PZ! (we had two...) too. In the end we got exclusively positive feedback from the people we interacted with. Too bad it died due to inactivity when the server went down last year...
Anyway, give those fellas a fair chance. Let them establish their RP a bit and get used to them being around, yelling at them here won't change anything (exept you'll look like immature fools). You do your RP, let them do theirs.
