Yes, i see, that's an advertisement. But if the URL is cloaked or not, where's the difference? I don't see any.
And i can't imagine that people are banned for cloaked URLs, as i said, there's a good reason in AFF marketing to cloak them, and that is not to hide that one's earning with it.

@Tom

I thought it is ok to promote something in the signature, isn't everyone doing it?
If i have infringed against the forum rules, please say to me exactly what it is that i have done wrong, but when you say i have been dishonest or tried to hide something, that is not a fact but only your interpretation. I can say to you, that it wasn't my intention.
Is that ok?
