Is this breaking any rules for the game?

So my clan started a war this morning. Shorty after we got a request to join our clan from someone named cailie. Now cailie only stayed in our base for about 30-60 minutes and then left the clan, but before he/she left the clan they left a message in our clan saying that he/she is their #7 on the enemy clan and then shorty after we checked the base for the #7 and it had the words "I am cailie" spelt out using their walls....I have screenshots of everything but i just wanna know if this is even legal ..and its kinda fair cuz they got to see where our traps are and what we have in our cc...I can't put up the screenshots ATM cuz I'm on my phone..

It just highlights that clans should be more careful who they allow in before and during wars. Poor clan leadership really.

Its legal :) We do it all the time xD

Did you fill clan castles? If yes, empty them and put different troops
Also move all your traps in your bases

This way they'll mess up

Yes, it is allowed. It us annoying and underhanded, but legal and allowed if im not mistaken.

At least she was nice enough to tell you. You never know when our spy hits and leaves you

It's Legal.

Lol. Your own fault, kudos to the opponent imo.

I've always thought it would be an excellent idea to have 2 bases. One for prep day and one for war day, switch right before the buzzer. Same base, just different trap/tesla placement. Then encourage spies, maybe even make your clan "anyone can join".

I bet it would really screw the other clan up. Thinking you know where the traps are when it's wrong, is even worse then not knowing where they are, i think.

She's not breaking any rules.

Your people let her in.
