Among the moderators there is no distinction between removal of the DPF, catalytic converter or EGR. All are illegal and will be dealt with accordingly.
However, the reality is that there are about a dozen moderators for:
Threads: 268,326, Posts: 2,887,056, Members: 77,402, Active Members: 20,825 (as of the time of this posting)
There is no damn way to catch every thread and every post about defeating emission controls and other illegal activity. We can only act on those threads and posts that are reported-in from other members and also the blatantly obvious threads that moderators catch from a cursory scan of the forums such as those entitled, "How do I delete my EGR/DPF/cat" and also posts from people with a history of trolling and argumentative behaviour on the subject.
If you have a different experience, help us do some something about it by reporting offending threads instead of b!tching about it.
