There is a Community Led Account Help forum for getting advice about issues like this. I guess CM Nick thought you were having a connection issue so moved your thread to the Community Led Technical Support forum.
A ban for what they did while your account was hijacked is not impossible. However, if your account receives a ban, you appeal, and an investigating J-mod can find evidence that your account was hijacked then the rule violations may be forgiven. See the Banned Account [Info] thread by Malua for up to date info about bans. My main concern is that your hijacked account may have been used as a bot by the hijacker. Macro bans can be appealed even though Jagex might say in some places that it can't be appealed.
