Problem with Guild Quests

Many players are faking their suicide after introduction of guild quests, they drop their infamy in order to increase rewards, completing quests faster.
I'm trying my best to report those players, these type of players are also a problem to new players and my playtime, they'd loose interest and may quit the game.
I spend so much time trying to complete my quests ( hard as I'm a fixer) . These dumbos just ruin my interest.
Rovio please take action against these players, atleast impose a temporary ban, it's very annoying seeing my teammate running into enemies to Suicide, faking seems like he's fighting. From now I'll update those players name here, so everyone can have a look.

 

There is this MK5 Speeder on 3k infamy. I can't drop the name but his name sounds like the Mango fruit + Chi. He is carrying a legendary cannon and is suiciding on every game I played with him. That's probably what he's doing and it's so annoying as a team mate.

 

After Rovio spent so much time crafting the exact speed one can progress through the game, that seemed to get thrown out with the Guild Quests.... giving lots of incentive to do what you are saying, not to mention what Rovio's already corrected, and probably more to come.

 

Yes those guild quests actually help me to progress my game a bit faster, but players like these ruin my time, unless moderators impose a temp ban on these players this won't stop
