I would not worry too much about this. The impact of making a post in a thread is small.
In
Service Announcements, I've seen obvious scams almost reach the top of the list after a few people post in it (as a warning).
As a test, I've bumped
this topic on page 4. After my post, it was the 6th topic on the first page. I've removed my post again, it takes a bit longer to drop it down again.
