One thing players complain about a lot is there is no way to do a Permanent Block on another player such as spammers. A permanent block would mean you will no longer be able to interact or engage in play with the player you have blocked and they will not be able to interact or engage in play with you either. Facebook has this blocking feature perhaps game loft can employ the same feature. It would make the game more pleasurable for all.
As far as mute goes, it is only a temporary fix , every time a player logs back on players have to mute the same spammers over and again , this a an annoyance.
I hope game loft and devs can take this into consideration. See screen shot for example in post below.
