Do mods have the general right to edit signatures?

I have restored the link in my signature that got edited out a couple of times.

Whereas I could understand the motivation ( I had for an afternoon had in my sig that I had left ILP because of privacy infringement and unreliable mods ) the editing out of that link occurred days after I had deleted that notification, and then again a week later, so it seemed to be a matter of resentment.

If I am not allowed to use a link in my signature, please tell me straight out.

Maybe it’s considered advertising or something.

And… what? Did someone have a sudden moral change of heart?
As you may have observed, I’m not the only poster with a link to forums and other creations. The point is that I’ve had my forum link up since 2011, and it’s never been a problem before.

I don’t blame the mod for fucking with me a bit to mark a limit, but I hope it’s limited and temporary.

What privacy infringement?
