If they're lvl 98 and you're 57, they should also be more than 2 THs above you, so the loot penalty should stop them from stealing much resources from you. If you are around 900 trophies, you shouldn't care about losing trophies.
So if it's not a big resource loss, and the trophies aren't important, who cares if they destroy you. Just move on and attack the next base, keep on playing the game.
