Comment Parsing Can Create 404 Errors

[WillStrohl]

Describe the bug

Discovered in the DnnCommunity.org website... The comments engine does a good job of attempting to automatically link domain names in the comments. Perhaps, too good. If someone happens to be speaking about App_Offline.html for example, it thinks that you're trying to link to a website at App_Offlin.ht.

Software Versions

• DNN: 09.08.00
• Module: 06.05.00

To Reproduce

Steps to reproduce the behavior:

1. Install DNN & Blog
2. Configure the blog to allow you to create a new post.
3. Create a new post.
4. As any user, add a comment that mentions App_Offline.html. Do not include any other text that could potentially be a website.

Expected behavior

The comment is posted with no links/URLs.
