Yes, of course. But it's mostly a rhetorical question. You see, the new auto-complete filters are banning the terms of legitimate services (albeit theses services can be misused) in conjunction with terms of copyrighted works (e.g. <photoshop rapidshare> or <rapidshare photoshop>).
It's the combination of terms, so if one should be banned to please copyright holders, it almost makes sense to ban the terms of copyrighted works. After all, it's the copyright holders pushing for this kind of filtering.
Because they are probably available legitimately somewhere. Or the user might be looking for information about the work, not the work itself.
