There are tools for it. If something is written in a very sophisticated English. I always check. There are a number of short posts today which suggest to ask a question to Stackers are copied content and with minor changes, they are posted.

That's what downzaps are for. 

I likely miss almost anything that's copied from elsewhere. Seemingly AI content I usually ignore, because I'm not very confident in my ability to spot it.

Is it only I who is seeing so many AI generated and copy and posts (mostly via reddit) posts today? One or two new Stackers continuing the same way even after they had been suggested not to do it.
