I know that you want me to name a good Bot ot Botting service, that you can use, and get all those 99's real quick and, in RuneScape terminology, Pwn this game.
But I'm going to have to disappoint you here. The answer to your questions is No.
After the Bottany Bay update, Mod Mark stated that it is increasingly easy for them to identify and ban bots.
Here's Mod Balance on the number of bots they ban:
Additionally, the Runescape Player base (how much ever of it is left, that is) is extremely active on reporting suspicious and potential bots.
Not to mention you will be permanently banned. That's all of your bank and skills gone.. Forever.
And hey, it's just a game. So play it for the essence of it than trying to have a sense of achievement on a virtual level, while cheating your way to it. Level 99's are no big deal. Nor are completionist capes.
Enjoy, that is what the game should be to you.
