Take it easy, im being serious. Just days before i got banned i was tagging Hideouts on twitter for that Aoi fella and thinking "it wouldn't happen to me". I drop the 25 kills game, requeue, get into the next game and got obliterated. I had like 2-3 kills, 8-10 respawns and suddenly i am hit with the "This account have been banned" screen. My heart sunk because you just know you ain't winning that battle via automated EA appeals.
I get that you may enjoy Wildcard as other modes, especially in current map rotation, are not very enjoyable experience but if i take my account back anyhow i'd legitimately stay away from Wildcard until Respawn/EA addresses it publically. It is a fun mode but man... getting banned over not properly adjusted system to account for the high kill nature of the game mode is ridiculous.
As for the reasoning, it has to be "report amount based", say 100 or whatever or Kill/damage/accuracy. I have some foggy memories back when ZuniUK got banned Redspider said something along those lines (about 100 reports).
