Well it's not ENTIRELY fake. servitors are definitely a real thing and that method shares a lot of other techniques to create them but I think you should be aware of the time frame most people will work on a servitor for. Man people can spend a number of days if not weeks fully designing their servitor and getting a proper feel for them, after that they'll do as you program them too. You can get them to be a minion or more of a partner, that's up to you.
It's also a little more complex than just drawing a figure and letting it come to life you need to feed your own energy into the creation and fully visualize it's manifestation. You need to be fairly adept at energy manipulation first so if you're new you may want to get some practice in before you try it.
There's plenty of forum posts on servitors if you want to look for some more information on them, I'm sure some of the other members have explained it far better and in much more detail than I have here before too.
