Reddit rolled out some wacky automatic moderation lately, that shadow-hides comments based on keywords, and optionally issues warnings to the users. Its severity depends on the particular subreddit. The beauty of it, of course, is that it doesn't take any context into account, and in fact doesn't involve a human until an appeal (if at that, even). Moreover, discussion of Reddit moderation itself may also be hidden.

You might've not been aware of it unless you've opened the threads in which you participated, in an incognito tab.

I was a ‘top 1% contributor’ in a subreddit (which I only discovered when opening new Reddit in an incognito tab) and had many productive conversations, until the mods banned links to sites that I used, started requiring links to sites that are blocked in my country, and removed my comment over it. Quickest I ever quit a community.
