Sadly there is nothing we can do as the forum community nor the Game Devs. 

Some choose to hit with quantity of people to overcome a few and even if its not fairplay the best advice I can give you is spending your rss to below your catacomb limit and hiding all troops you receive.

Doing so will make your enemies waste lots of raid attempts on you, and even tho you may burn for a couple days. In the long run they will get bored of burning you and eventually stop.

Second option is to get your league mates/alliance defense trap you. Gonna be hard with that amount of players attacking but its doable!
