Designers: What do you do when you find a forum that removed your copyright?

[Audentio]

Then what are we talking about?

I would think that would be obvious, no? Theme copyrights and/or the violation of the copyright (i.e removing or breaking a different statement).

Affiliation is different. It has little to do with work being violated. In most cases, affiliation links are used to express support or gratitude to a website for either a service or requirement for a service. They are never bound by any means to keep that link on there, it is always at their own discretion.
