Thanks for bringing this glaring UI issue to light. We’ve implemented your MD fixes for titles on Prod Beehaw now. If that change creates any unforseen issues please let us know of course.

So yeah… titles are fully parsed as markdown. Which opens up a lot of abuse vectors for spammers/scammers. Not only that, links in markdown are green which opens the door even further for fake admin posts.
