MSN comments section has certain stuff that it won't let you post - this includes a whole load of defined words.

Medium could stop anyone from being able to post 'contact me on WhatsApp'. That would get rid of one level of automated spam.

They could buy the rights to run all stories through, say Hive AI detector at the point where someone presses publish. And anything that gets a figure of 50% AI or more could demand revisions before the piece can be published.

That would make sense to me.
