Car Talk site manager’s to the rescue please! A troll has taken over the site.
Spam messages have been deleted.
Unfortunately, when those spam posts were deleted, the “recent changes” timer on the post was left set at the more recent date, so all these old threads have swamped the more recent ones. The most recent change timer really should be set back to the time of the last undeleted post. Maybe the board admins can fix this in a software setting, or maybe the vendor of the board software can write a fix for this. It would be worth asking about.
