Since I am a moderator, I can talk a little bit about the process in general.
First of, everyone on Microsoft Q&A can report a post, and the post will then be reviewed a moderator who may:
- Approve the post.
- Delete the post.
- Just pass and do nothing.
I have found that indeed very old posts can be reported. And in many cases for no good reason, and I approve those posts. But occasionally I agree with the report. I seem to recall a two-year old post that was reported the other day. When I looked at it, it seemed to be answering the question, but then all of a sudden there was a link to a business of some sort that had no relation to the question. That is a spam pattern, we see every now and then.
There are many moderators, and it is evitable that we have our bars on different level. Where I would have approved a post, another moderator would have deleted it.
For your actual post, I can't comment, since I don't know anything about the issue. I don't think it was me who deleted it - but I am not going to swear on it. If you have a link to the question, we can take a second look.
