Believe it or not, this is actually a vBulletin "feature". We reached out to vBulletin technical support and here is the reply we received.

It would be the hashtag bbcode. It will link to nodes by their ID number.
There is no way to remove that small piece of functionality at this time. You would have to turn off the hashtag bbcode completely. Settings → Options → BB Code Options. Uncheck Hashtag. Or surround it with noparse tags.
edit:
When I proposed the hashtag functionality, I figured linking to nodes would be very useful shorthand. The system already has a node bbcode and this just builds on that functionality and exposes it now. So if someone want to link to this channel (or more commonly a topic) instead of going:
Support Issues and Questions
or
https://www.hrwforum.com/node/111
They can just type…#111

Note the portion of the feedback that reads, "...there is no way to remove that small piece of functionality at this time."
Workarounds:
Enclosed the number in quotes - "#9"
Use No. 9 instead
Use # 9 instead (add space between "#" and number - e.g. # 9)
