Player's clan history - A remedy to some unfairness in wars
Second time this happen to my clan in a year: we declare war; some time (hours) after a match is found, a new player gets accepted into the clan - usually they're high ranking players, people you'd want in your clan.
The player was actually in the opposite clan, and entered into yours just to communicate strategies, bombs' and teslas' locations, castle troops, whatever they want.
The player left shortly after the war ended. Someone in my clan took a look at the opposite clan, and there he was, co-leading.
In this case the player was [edited: ask for details] from clan [edited: ask for details]. War with my clan took place between 18 and 19 october. And yes, I'm being so specific because I hope some action will be taken against these people. And yes again, we won anyway :p.
I'm not off-topic, though. This is unfair play, and we know it, but there's no rule against it. So, at least the leader of a clan should be able to see the last clans a player was in before getting into his own. That way if you're cautious enough you can outsmart these losers. Else, the only way to be safe is just not accepting new players during war, which is kinda frustrating, if you're always at war (my clan is).
If this is not possible, I'm seriously thinking about making a blog for reporting unfair players, as a database.
Totally unrelated topic: please increase the number of different military ranks: 4 is just not enough, and people would partecipate more in clan's life if they could make a career and gain levels (gaining levels makes you invest more energy on something... mmh, where did that come from?)
Thanks in advance, and please let me know if I can/should report player and clan somewhere else.
Your own clans irresponsibility
I see this as your own clans irresponsibility that you let a spy into your clan. I also see "spying" as a valid war strategy (even though my clan doesn't do it). If you want a good trick to stop spy's I suggest that as soon as war starts you get a member of your clan to screen shot some pictures of they're clan members and check when you let people in to make sure they are not from the opposing clan.
