Messaging when clicking on a notification email that is out of date

In a forum, users can get email notifications of new replies, etc. as they happen.

The links and content of the email are based on what topic received the reply, etc.

After the email goes out, any number of things can happen to the reply. It can be split into a new topic, converted to an article, deleted, merged with another reply on the same topic, merged with another reply on a different topic, merging a reply into the original post, original post can be renamed/redirected, etc... there are about 20 such scenarios.

The system I am working with is designed so that when the user clicks the link in the notification email, they would be taken to the appropriate page based on any merges, conversions of replies to new topics, etc.

Messages can be configured for the cases where the user would land somewhere different than shown in the email.

My question is - is it helpful or not to show a message for each of these scenarios? I have tried coming up with some verbiage, but it all feels WAY too complicated. Is it better just to land the user in the appropriate place?

Here are the examples I have for some of the scenarios:

• The reply was converted to a new post, shown below. To view the original topic, visit {{original_link}}.
• The contents of the new reply was merged into the original post.
• The contents of the new reply has been moved and merged into the post shown below. To view the original topic, visit {{original_link}}.
• The reply has been removed and is no longer available
• The new reply was merged into another, and the pair were split out into a new topic shown below. To view the original topic, visit {{original_link}}.
• The contents of the new reply was merged into the original article.
• The new reply has been moved and merged into the article shown below. To view the original page, visit {{original_link}}.
• The reply has been removed and is no longer available.
• The new reply has been moved and merged into the article shown below. To view the original page, visit {{original_link}}.

Again, I feel this is way too convoluted and goes against the "don't make me think" philosophy. Is it just too verbose, or should I do away with these altogether? (except maybe the ones where the reply is simply deleted and no longer available?)

Wikipedia, for example just uses phrasing something like "{source page} redirects here" but it seems that in my case the scenarios are more complex, and in my case, the users are clicking from an email link, and not simply discovering content through internal linking as on wikipedia.
