1- We level our characters to learn the in's and out's of our characters. If you don't personally take the time to level your character, you aren't going to be able to play it to it's maximum ability.
2- In order to use a speed leveling service, you must give them your username and password, obviously, or they would have no other way to access your account. With your username and password, they have access to whatever they want on your account - not just your characters but your personal information that is saved under Account Management, as well.
3- There are quite a few "speed leveling services" out there that actually just steal your account and then sell the gold. If that were to happen, there's nothing that you can do about it. You can't report it to Blizzard, because it's against the Terms & Conditions to use a speed leveling service in the first place, so now you're further behind than you were at the beginning.
4- It just makes you look silly. Plain and simple.
So really people, don't waste your money to use speed leveling services - level your character yourself. Even more importantly, don't buy gold online - earn your own gold through the hints and tips that I give you here.
