Help! I can't make a signature!

[user 219916]

It tells me that my content is spam-like or inappropriate every time I try to save my signature. It says to contact an administrator, but I have no idea how to do that either..
I'm not sure if this is the right place to post this, but I can't find a help board.

Try disabling any hyperlinks.

How do I do that? It has me upload the image as a link.
