But what is there to stop a spammer from doing the same?

I mean it's fairly easy to grab the captcha code and run it 
through a D compiler and then post the result automatically.

It's no rocket science, so it really doesn't do much in 
preventing I think.

Really it can be automated like:

1. Copy the code
2. Go to run.dlang.io
3. Paste the code
4. Compile it
5. Wait for the output
6. Copy the output
7. Paste the output into the input field
8. Submit

It would take anyone familiar with basic http macros less than 10 
minutes to automate that process, even less using a programming 
language if it's mass automation.

The forums for D might just not be popular enough for any "bots" 
to bother I guess?

I would suggest some real captcha software that are used by the 
majority of sites.

And on top of that maybe a flag system.

People being able to flag posts and if a specific post is flagged 
by enough people then it'll be "hidden" until moderation takes 
action by either making it "visible" again due to invalid 
flagging or deleting it because it was a valid flag.

This can help not only against spammers, bots etc. but also when 
there are trolls making troll posts etc.
