I'd complain to the owners if I was you.
You would definitely have left if I owned the site!
Ah! That explains why I sometimes get a "post missing" message.As mod7 says, the links you receive in email notification go directly to the new post. In the event of that post being removed (in this case because they were spam) the link no longer works.
The topic to which the spam post was added is not removed.
Unfortunately that actually seems to make total senseInstead of leaving you customers lost and wondering what has happened, could you not replace the deleted post by a post within the topic, similar to that from a Moderator, saying that the post has been deleted because it was spam etc.
Great.This is something that will hopefully be added in the future.
