You are welcome to complain, although I doubt it will get you anywhere. I'm not sure which post you are referring to, but Im not the only one deleting your off topic posts.

You do post things that are on topic and contribute to the conversation, and they are welcomed.

But, once again, off topic posts, SPAMs, or posts violating the TOS will be removed. If you don't like there are other boards you can go to.
