I'm a bit "OCD", so I don't like letting threads with the "New Post" (aka "unread") icon.
Currently, I do click on threads (to remove the "New Post" status") or click on "Mark all Read".

However, there are threads that are a bit harder to ignore sometimes (but I still prefer to ignore them).

Is there currently any way to automate ignoring certain threads that I might have missed?

If not (and I might be hoping for a lot here but), I would love if there was an option to do so.
The same way there is an option to "follow" a thread, there would be one to "ignore/block" a thread.

My own self-restrain can do the trick (usually), but that would just be that more comfortable 😅
