I am with you. Some time ago I opened a thread in meta about a similar case:

How to deal with multiple, factually incorrect threads?

The only thing I would'nt have done is to self-moderate the thread. That will cause it to have fewer replies and you may find several other threads with more replies than keep being bumped while yours dies.

If you are pissed off that people don't read and say false information you can try reporting it but you may have not much success reporting for false information.
