Why are threads discussing "illegal" material locked?

[Phantasus]

Im just wondering why threads that are discussing "illegal" material (aka. Music videos, fansubs ect..) are closed?

I just checked the rules and it dosent say that you aernt able to discuss these things.
I can understand the rule against posint links ect. to these files but why is the discussion of them not allowed?

Because they are festering sores which are begging for someone to post a link.

Not all of these threads are closed though, it depends on the mood of the thread, if its inevitable that someone is going to ask for a link or post a link the thread is closed.

Some of these threads go for weeks before they reach the point of being closed, others its immediate.

Finally with having the desire to get companies involved in funding AB does not want to be associated with people 'discussing' illegal material.
