I would say yes and no. An account i was using botting on it got hacked but not sure if it was epic bot. You should powebot epicbot but don't enter details untill you have around 4m and then just buy an auth to an rsbots.net script.
It is safe at the moment, but you never know what they are up to ( seeing the recent happenings of Powerbot ), if you want to be fully safe just use Rsbots.net.
If you really don't want to pay for auths then use EpicBot, but change your password after every botting session.
