Yes the thread is being moderated as can be seen by the many removed posts. Those that have been on this thread since it started will see that more than 10 posts were removed from just the first page. The Audiogon staff must have their hands full dealing with threads, on top of the new Site going live.
If you see suspicious posts, it looks like when logged in as a member, there is now on each thread a "Report this" button on the OP (Original Post) . You can also email audio support.
