Getting rid of the trollbox on Cryptopia

Currently using Cryptopia to learn about trading coins. Trouble-free interface, low fees, etc. make it a nice exchange for me.

However, that useless trollbox feature is very annoying. I'm using an internet connection with a really low bandwidth (gets reduced drastically when the monthly traffic is used up) and I'd love to find a way to block that chatbox. Tried manually closing the connection (used TCPview for that) and it does work (frees up the bandwidth), but of course the stupid box reconnects to its server immediately.

Any IT-savvy folks around here know how I could disable that box? Will have a decent internet connection again in a couple weeks, but I'm not willing to wait (and just read about trading instead of learning by doing).

Help would be appreciated.
