You make an interesting point.
The first thing I'd like to say is that, to the best of my knowledge, I am directly not helping spammers in any way with this bot. As of writing this comment, the source code for the bot is not public, and so, without access to that private source code, spammers could not use that code for any purposes.
Another thing to say is that Daily Developer Jokes uses the DEV API, which provides the ability to create posts via a basic POST request to any DEV user give post data and a valid API key. So, in theory, anyone could use that API endpoint to create automated posts. In fact, one DEV member has made a Chrome Extension that utilizes the API to schedule posts (see article). The DEV API imposes "a limit of 10 articles created each 30 seconds by the same user", which the Daily Developer Jokes abides by.
Lastly, I'd like to just agree with @khrome83
, in that Daily Developer Jokes provides unique content, just in an automated fashion. From what I can tell, Daily Developer Jokes abides completely with the DEV Code of Conduct.
It would be interesting to see if more bots on DEV start appearing, and if and how DEV staff will react to that.
