One thing that has been a pretty sore spot for some people trying to access this forum is that the CAPTCHA system as it is, is so tough. If you aren't an absolute fan of the classic Doom series there's a good chance you won't be able to answer most of them on your own.
The idea has always been that you could go to live chats like IRC, Discord, or Matrix, and ask the question there and someone knowledgeable would be able to help you. But some people are just shy and don't want to use that option.
On the counter end of this though, we've been having actual humans or very intelligent bots (probably a bit of both) bypass the CAPTCHA system with simple questions that are more common knowledge.
The questions we have right now are very tough. They've managed to weed out all but 3 spam-bot incidents in the past few months. That's actually very good. The problem is, it's too tough sometimes for actual legitimate users - as it stands, the forum can really only grow with people who know a lot about the original Doom series. That's not very conducive to a community that encourages the sharing of ideas and works for others to enjoy and learn from.
So the idea I had was this: What if the CAPTCHA system as it is was completely revamped to require you to download a version of ZDoom or GZDoom along with shareware versions of Doom and/or Heretic, use cheat codes to freeze the level and warp to certain points, and describe what you see on your screen, instead? It'd be a simple question like "What is the monster shown in E1Mx of Shareware Doom at point (xxx, yyy) when the player is facing north?" It could include a link to the bestiary of either game so that prospective users would know what to type and how to type it to pass the CAPTCHA.
I am not really sure if I like this system, though: First, it requires running an external program, second it could be easily defeated by a specially written bot that can look up the level data on its own.
I am open for ideas and discussion on this topic - however, I will not entertain any ideas which have the potential to greatly increase the workload of the site's moderators.
