A few years ago when the grapes came out in the cove, a few users abused a glitch allowing them to refresh multiple times at the cove on one account without a ban. If you were ever on the battldome chat, you would have already heard about this. Firebreath###, and some other oldies with established accounts abused this and later admitted. None of which were frozen for doing this glitch. Apparently, they refreshed the cove over and over in browser offline mode or something. Apparently theres an addon or setting which alerts you once the page you are on has been updated. In this case, an update would be an restock==== profit. You would switch to back to online and buy. Game over.
Now, if this still hasnt been patched... it could rape the cove and shops which dont restock much (MP, BA, DM, BM, shells etc). Pretty much if someone actually remembers the method, or has an idea to implement this into a program, it would greatly benefit clraik. Also, the method of using 100+ accounts as a backbone for refreshing is NOT what I am talking about lol. Those programs have already been made. This uses a single account (and possibly the program using another in offline mode).
