Technically, you can.

as a th7 you can be looted 250k. A th8 would have a 10% penalty so could raid 225k from your storages, so it would be about 450K if you have near full storages from TH8's, 500K if it was another TH7. That's not including mines/pumps which have a different cap system.
And yeah, as they said any TH8 will steamroll your base anyway (maxed or otherwise).
Putting TH off to the side hoping for snipes are your best bet. That, or just make sure to spend the majority of your loot. Have loot and you will be raided regardless, just name of the game
