Now, I can visit pages for certain medical conditions that contain completely unsourced claims with no "citation needed" nor any warnings. When I try to search for it, I often trace it back to alternative medicine or pseudoscience influencers.
The sad part is that when I've tried to remove obviously flimsy information, someone will immediately come along and add it back. Unless you're ready to spend months in a Wikipedia edit war with someone who obsesses over a page, there's no point in even trying. These people know the rules and processes and will use every one of them against you. When that fails, they'll try to pull rank. If that fails, they'll just quietly continue editing and rewriting (possibly from alt accounts) until you get too tired to fight the battle any more.
