So you guys are fine with gaming stats and gaming shooting a player over and over again to game the ranks and stats. This undermines the integrity of the system, in typical Jokers fashion who are fine with ruining the game I guess.
Come on. Yall are better than that. 
First off it is a waste of time to compare yourself to anyone else in scores/ranks. They can easily be twisted....case in point. The score/rank system doesnt show the skill of a player, only what they do in the game. Most of the high ranking fighter guys are pick and runners, would you call them good fighters? Not me Id call them very good pick and run artist. The scores are just a "general" way of ranking players.
How others play the game is just that, how "they" play the game. There is a rook squad that is known for only dropping below 10K when they are running home with their handful of picks, but it the way they want to play. If a squad is on and loves rolling undefended bases then they can do that, but wouldnt that skew the base takes in both GVs and Goons (it does), which then skews the bomber and GV ranks/scores. Players are always messing with the score whether they mean to or not.
Then you have the blatant ones like the one called out in the OP. More than likely a kid looking for a fast way up the scoring sheet. Had he been a little smarter about it it may have slipped by for months more. Having been let back into, or never having been kicked out shows either the squad doesnt care or the player has been told its uncool to blatantly manipulate your score like that and please stop. Either way unless Hitech gets into it that is the extent of what the squad can do.
Finally, do I care? No, because I dont use the scores and ranks to compare myself to other players. Some players get to play 60-100 hours a month, that skews a number of ranks in their score/ranks totals. Some players jump from team to team always in the action which again skews scores and ranks. There are so many ways of player this game that the score system could NEVER give a true score/rank of the players.
I only use the scores and ranks to compare my skills to my skills. I practice buff runs to keep my timing sharp on flattening towns. Some call it "milk runs", but when my squad needs me to flatten a town there is a good chance Ill get it done. Hit percentage is important to me in a bomber, but only mine. Its the same in fighters. I have set a goal for each tour. 2.0 k/d, 1.0 k/s and a hit% over 5 Awesome numbers compared to others? Dont think so, on the other hand, dont care. Its a goal I set for me. Some times its hard, the squad may need me to dive through a half dozen fighters to get the last couple of guns down at a field and I do it. Doesnt do wonders for my score/rank, but it helps out the squad, after all thats why you join a squad right? To work together and help them out accomplishing a mission.
So you play the game the way you want, and others will play the game the way they want. In the end if Hitech comes in a slaps someone for shooting a 2nd account down time after time then thats the way it will be. Until then all we can do is play.
