is there anything the authorities can get involved with?

or maybe FReeper IT guys that could help out with?

Literally nothing you can do in these situations except blacklist entire IP ranges if needed. You can’t really take legal action because most of the IP traffic doing the attack are bots that reside on hacked or malware ridden computers. This isn’t uncommon with large traffic systems especially financial institutions.
