Sorry, but I don't think you fully understand how the patent system works. Examiners generally look at published patents and patent applications. Even though they theoretically can, they don't look at abandoned patents that were never published (generally called secret 102(e) art). Also, filing a true patent application is pretty expensive, minimum $5k to do it properly. There are inexpensive options, such as provisional patent applications which can be as low as ~$100, but examiners don't look at those either.

If you're worried about someone patenting something you created, and you don't care about getting your own patent protection on your invention, you'd likely get more mileage from publishing a detailed blog article than filing a patent application.
